fix check macro expansion
If the only argument to `check!` is the module name I get this error:
```
error: expected expression, found `,`
--> src/tools/tidy/src/main.rs:63:42
|
57 | / macro_rules! check {
58 | | ($p:ident $(, $args:expr)* ) => {
59 | | drain_handles(&mut handles);
60 | |
... |
63 | | $p::check($($args),* , &mut flag);
| | ^ expected expression
... |
69 | | }
70 | | }
| |_________- in this expansion of `check!`
...
117 | check!(hey);
| ----------- in this macro invocation
```
This change makes it so commas are added only when there are `args`.

check for x version updates
This PR adds a check to tidy to assert that the installed version of `x` is equal to the version in `src/tools/x/Cargo.toml`. It checks the installed version of `x` by parsing the output of `cargo install --list` (as an option proposed in this [issue](https://github.com/rust-lang/rust/issues/106469)).
It does not warn if `x` has not yet been installed, on the assumption that the user isn't interested in using it.

document + UI test `E0208` and make its output more user-friendly
Cleans up `E0208`'s output a lot. It could actually be useful for someone learning about variance now. I also added a UI test for it in `tests/ui/error-codes/` and wrote some docs for it.
r? `@GuillaumeGomez` another error code, can't be bothered to find the issue :P. Obviously there's some compiler stuff, so you'll have to hand it off.
Part of https://github.com/rust-lang/rust/issues/61137.

Remove double spaces after dots in comments
Most of the comments do not have double spaces, so I assume these are typos.

Add tidy check to ensure that rustdoc GUI tests start with a small description
The first commit comes from https://github.com/rust-lang/rust/pull/106865 to prevent CI to fail.
This PR adds a tidy check to enforce having a small description at the top of the GUI test. Although the format is made to be as easy as possible to read, it's not always obvious what a test is actually checking. I think enforcing this will make it easier for us to come back on these tests if needed.

tidy: Don't include wasm32 in compiler dependency check
This changes the tidy compiler dependency check so that it does not include wasm32-unknown-unknown dependencies in the PERMITTED_RUSTC_DEPENDENCIES. This just helps keep the list cleaner under the assumption that the compiler will never work on wasm32-unknown-unknown.
This also fixes a bug in the check to verify there are no unused dependencies in the PERMITTED_RUSTC_DEPENDENCIES. Previously the check was verifying that the dependency was used *anywhere* in the workspace, when it should have been checking if it was used for the compiler.
There's also just a little general cleanup here. For example, the old `normal_deps_of_r` function was changed a while ago to return *all* dependencies, but the function name and description wasn't updated to remove `normal_`.

Remove duplicate sha-1 dependency
[`sha-1`](https://crates.io/crates/sha-1) is more or less a duplicate of [`sha1`](https://crates.io/crates/sha1). The `sha-1` is deprecated and no longer updated. This updates the dependencies to use the new name.
Some other dependencies that got updated as a consequence:
* The updated pest dependencies are currently only used by mdbook, and shouldn't have any issues.
* ucd-trie 0.1.3 to 0.1.5: No changelog, but looks like some tables were updated for new unicode versions: https://github.com/BurntSushi/ucd-generate/commits/master/ucd-trie. This is only used by pest (and thus mdbook).
* thiserror 1.33 to 1.38: Nothing significant in the notes at https://github.com/dtolnay/thiserror/releases.

remove unreachable error code `E0490`
AFAIK, the untested and undocumented error code `E0490` is now unreachable, it was from the days of the original borrow checker.

Revert "warn newer available version of the x tool"
Reverts rust-lang/rust#104552
Running the x executable directly created an [issue](https://github.com/rust-lang/rust/issues/106469) here. There are other options for warning a user that a newer version of x exists in the issue's discussion as well.

error-code docs improvements (No. 2)
- Added empty error-code docs for `E0208`, `E0640` and `E0717` with the "internal" header as discussed on Discord.
- Wrote docs and UI test for `E0711`, again with the header.
- `tidy` changes are common-sense and make everything pass, `style.rs` hack is annoying though.

remove unreachable error code `E0313`
Fixes #103742
Makes #103433 redundant
Implements removal of `E0313`. I agree with the linked issue that this error code is unreachable but if someone could confirm that would be great, are crater runs done for this sort of thing?
Also removed a redundant `// ignore-tidy-filelength` that I found while reading code.

Add some UI tests and reword error-code docs
Added UI tests for `E0013` and `E0015`. Error code docs for `E0015` were a bit unclear (they referred to all non-const errors in const context, when only non-const functions applied), so I touched them up a bit.
I also fixed up some issues in the new `error_codes.rs` tidy check (linked #106341), that I overlooked previously.

Update `rand` in the stdlib tests, and remove the `getrandom` feature from it.
The main goal is actually removing `getrandom`, so that eventually we can allow running the stdlib test suite on tier3 targets which don't have `getrandom` support. Currently those targets can only run the subset of stdlib tests that exist in uitests, and (generally speaking), we prefer not to test libstd functionality in uitests, which came up recently in https://github.com/rust-lang/rust/pull/104095 and https://github.com/rust-lang/rust/pull/104185. Additionally, the fact that we can't update `rand`/`getrandom` means we're stuck with the old set of tier3 targets, so can't test new ones.
~~Anyway, I haven't checked that this actually does allow use on tier3 targets (I think it does not, as some work is needed in stdlib submodules) but it moves us slightly closer to this, and seems to allow at least finally updating our `rand` dep, which definitely improves the status quo.~~ Checked and works now.
For the most part, our tests and benchmarks are fine using hard-coded seeds. A couple tests seem to fail with this (stuff manipulating the environment expecting no collisions, for example), or become pointless (all inputs to a function become equivalent). In these cases I've done a (gross) dance (ab)using `RandomState` and `Location::caller()` for some extra "entropy".
Trying to share that code seems *way* more painful than it's worth given that the duplication is a 7-line function, even if the lines are quite gross. (Keeping in mind that sharing it would require adding `rand` as a non-dev dep to std, and exposing a type from it publicly, all of which sounds truly awful, even if done behind a perma-unstable feature).
See also some previous attempts:
- https://github.com/rust-lang/rust/pull/86963 (in particular https://github.com/rust-lang/rust/pull/86963#issuecomment-885438936 which explains why this is non-trivial)
- https://github.com/rust-lang/rust/pull/89131
- https://github.com/rust-lang/rust/pull/96626#issuecomment-1114562857 (I tried in that PR at the same time, but settled for just removing the usage of `thread_rng()` from the benchmarks, since that was the main goal).
- https://github.com/rust-lang/rust/pull/104185
- Probably more. It's very tempting of a thing to "just update".

refactor: clean up `errors.rs` and `error_codes_check.rs`
`errors.rs` is basically unused now, `error_codes_check.rs` is useful but not well commented, etc. It also doesn't check certain things which are certainly not correct. For example, `E0505` has a UI test in `src/test/ui/error-codes/` but that test actually outputs `E0504`?! Other issues like these exist. I've implemented these with "warnings" which are a bit rough around the edges but should be removed eventually.

warn newer available version of the x tool
This PR adds a check to `tidy` to assert that the installed version of `x` is equal to the version in `src/tools/x/Cargo.toml`. It adds a `--wrapper-version` argument to `x` to determine the version at runtime, .
It does not warn if `x` has not yet been installed, on the assumption that the user isn't interested in using it.
