compiler: Add Windows resources to rustc-main and rustc_driver
Adds Windows resources with the rust version information to rustc-main.exe and rustc_driver.dll
Invokes `rc.exe` directly, rather than using one of the crates from the ecosystem to avoid adding dependencies.
A new internal `rustc_windows_rc` crate has the common build script machinery for locating `rc.exe` and constructing the resource script

Update tracing and fix binary regression
Previous attempts (rust-lang/rust#127316, rust-lang/rust#134770) saw binary size regressions, this was root caused to <https://github.com/tokio-rs/tracing/pull/2553> which changed the behavior of the `max_level_info` feature flag to match the docs (i.e., that flag only applies for debug builds and `release_max_level_info` applies for release builds).
This change bumps the `tracing` version and sets both `max_level_info` and `release_max_level_info` when to match rustc's own `max_level_info`.

eagerly compute `sub_unification_table` again
Previously called `sub_relations`. We still only using them for diagnostics right now. This mostly reverts rust-lang/rust#119989. Necessary for type inference guidance due to not-yet defined opaque types, cc https://github.com/rust-lang/trait-system-refactor-initiative/issues/182.
We could use them for cycle detection in generalization and it seems desirable to do so in the future. However, this is unsound with the old trait solver as its cache does not track these `sub_unification_table` in any way.
We now properly track the `sub_unification_table` when canonicalizing so using them in the new solver is totally sound and the performance impact is far more manageable than I thought back in rust-lang/rust#119989.

The symbols __isPlatformVersionAtLeast and __isOSVersionAtLeast.
This allows the user to link both compiler_rt and std.

- added full urlencoding to properly check urlencoded anchor links against non-urlencoded heading IDs
- added tests

there is no reason this should not work, really, we're just cutting some scope for now

That test causes a large amount of crashes. If a system
has a /proc/sys/kernel/core_pattern that uploads core dumps enabled,
it will take a long time to complete. Set dumpable to 0 to avoid that.
Before:
$ time ./panic-uninitialized-zeroed
real 0m47.457s
user 0m0.023s
sys 0m0.021s
After:
$ ./panic-uninitialized-zeroed

Fix typo in default.rs
This sentence currently reads:
> Rust implements `Default` for various primitives types.
I think it should just be "primitive types".

docs(std): add error docs for path canonicalize
This PR adds the missing error documentation for both [Path.canonicalize](https://doc.rust-lang.org/std/path/struct.Path.html#method.canonicalize) and [PathBuf.canonicalize](https://doc.rust-lang.org/std/path/struct.PathBuf.html#method.canonicalize) methods. Since both methods are wappers around [fs::canonicalize](https://doc.rust-lang.org/std/fs/fn.canonicalize.html), the error doc is copied directly from that function.
This makes it faster to find what errors might arise when calling `path.canonicalize` or `path_buf.canonicalize` in the editor itself without needing to drill down to the `fs::canonicalzie` docs.

GVN: Ensure indirect is first projection in try_as_place.
I haven't found any report for this bug on existing code, but managed to trigger it with rust-lang/rust#143333

Migrate more things in the new solver to specific `DefId`s
Continuation of https://github.com/rust-lang/rust/pull/145377. I migrated the rest of the types, except aliases.
Aliases are problematic because opaques and associated types share the same type in the new solver. `@jackh726,` `@lcnr,` `@ShoyuVanilla` I'd like to hear ideas here. Anyway, even if we do nothing with them we already got a substantial improvement.

improve c-variadic error reporting
tracking issue: https://github.com/rust-lang/rust/issues/44930
The parts of https://github.com/rust-lang/rust/pull/143546 that don't require any particular knowledge about c-variadic functions.
This prepares the way for rejecting c-variadic functions that are also coroutines, safe functions, or associated functions.
