Port `tests/run-make-fulldeps/hotplug_codegen_backend` to ui-fulldeps
This is the last remaining run-make-fulldeps test, which means I actually had to leave behind a dummy README file to prevent compiletest from complaining about a missing directory.
(Removing the run-make-fulldeps suite entirely is non-trivial, so I intend to do so in a separate PR after this one.)
---
I wasn't sure about adding a new kind of aux build just for this one test, so I also tried to just port this test from Makefile to [rmake](https://github.com/rust-lang/rust/issues/121876) instead.
But I found that I couldn't get rmake to fully work for a run-make-fulldeps test, which convinced me that getting rid of run-make-fulldeps is worthwhile.

Clarify our tier 1 Windows Server support
I've been asked a number of times about our minimum Windows Server support so this PR updates the documentation to be more explicit.
Note that this doesn't change our support at all, it just clarifies it. Windows Server 2016 is the first "Windows 10" server OS (specifically it has the same [build number](https://en.wikipedia.org/wiki/Windows_Server_2016#Release_to_manufacturing) as Windows 10 1607).

Handle no values cfgs with `--print=check-cfg`
This PR fix a bug with `--print=check-cfg`, where no values cfgs where not printed since we only printed cfgs that had at least one values.
The representation I choose is `CFG=`, since it doesn't correspond to any valid config, it also IMO nicely complements the `values()` (to indicate no values). Representing the absence of value by the absence of the value.
So for `cfg(feature, values())` we would print `feature=`.
I also added the missing tracking issue number in the doc.

ARM Target Docs Update
Updates the ARM target docs, drawing more attention to the `arm-none-eabi` target group by placing all targets *within* that group as a sub-list in the Table of Contents.
Also updates the `armv4t-none-eabi` page (maintainer signoff: I'm that target's maintainer) to clarify that the page covers the arm version and the thumb version of the target, but that the target group page has the full info because there's nothing really specific to say for those targets.

Show files produced by `--emit foo` in json artifact notifications
Right now it is possible to ask `rustc` to save some intermediate representation into one or more files with `--emit=foo`, but figuring out what exactly was produced is difficult. This pull request adds information about `llvm_ir` and `asm` intermediate files into notifications produced by `--json=artifacts`.
Related discussion: https://internals.rust-lang.org/t/easier-access-to-files-generated-by-emit-foo/20477
Motivation - `cargo-show-asm` parses those intermediate files and presents them in a user friendly way, but right now I have to apply some dirty hacks. Hacks make behavior confusing: https://github.com/hintron/computer-enhance/issues/35
This pull request introduces a new behavior: now `rustc` will emit a new artifact notification for every artifact type user asked to `--emit`, for example for `--emit asm` those will include all the `.s` files.
Most users won't notice this behavior, to be affected by it all of the following must hold:
- user must use `rustc` binary directly (when `cargo` invokes `rustc` - it consumes artifact notifications and doesn't emit anything)
- user must specify both `--emit xxx` and `--json artifacts`
- user must refuse to handle unknown artifact types
- user must disable incremental compilation (or deal with it better than cargo does, or use a workaround like `save-temps`) in order not to hit #88829 / #89149

This commit sets the `target_env` key for the
`wasm32-wasi{,p1,p1-threads}` targets to the string `"p1"`. This mirrors
how the `wasm32-wasip2` target has `target_env = "p2"`. The intention of
this is to more easily detect each target in downstream crates to enable
adding custom code per-target.

GuillaumeGomez:stabilize-custom_code_classes_in_docs, r=rustdoc
Stabilize `custom_code_classes_in_docs` feature
Fixes #79483.
This feature has been around for quite some time now, I think it's fine to stabilize it now.
## Summary
## What is the feature about?
In short, this PR changes two things, both related to codeblocks in doc comments in Rust documentation:
* Allow to disable generation of `language-*` CSS classes with the `custom` attribute.
* Add your own CSS classes to a code block so that you can use other tools to highlight them.
#### The `custom` attribute
Let's start with the new `custom` attribute: it will disable the generation of the `language-*` CSS class on the generated HTML code block. For example:
```rust
/// ```custom,c
/// int main(void) {
/// return 0;
/// }
/// ```
```
The generated HTML code block will not have `class="language-c"` because the `custom` attribute has been set. The `custom` attribute becomes especially useful with the other thing added by this feature: adding your own CSS classes.
#### Adding your own CSS classes
The second part of this feature is to allow users to add CSS classes themselves so that they can then add a JS library which will do it (like `highlight.js` or `prism.js`), allowing to support highlighting for other languages than Rust without increasing burden on rustdoc. To disable the automatic `language-*` CSS class generation, you need to use the `custom` attribute as well.
This allow users to write the following:
```rust
/// Some code block with `{class=language-c}` as the language string.
///
/// ```custom,{class=language-c}
/// int main(void) {
/// return 0;
/// }
/// ```
fn main() {}
```
This will notably produce the following HTML:
```html
<pre class="language-c">
int main(void) {
return 0;
}</pre>
```
Instead of:
```html
<pre class="rust rust-example-rendered">
<span class="ident">int</span> <span class="ident">main</span>(<span class="ident">void</span>) {
<span class="kw">return</span> <span class="number">0</span>;
}
</pre>
```
To be noted, we could have written `{.language-c}` to achieve the same result. `.` and `class=` have the same effect.
One last syntax point: content between parens (`(like this)`) is now considered as comment and is not taken into account at all.
In addition to this, I added an `unknown` field into `LangString` (the parsed code block "attribute") because of cases like this:
```rust
/// ```custom,class:language-c
/// main;
/// ```
pub fn foo() {}
```
Without this `unknown` field, it would generate in the DOM: `<pre class="language-class:language-c language-c">`, which is quite bad. So instead, it now stores all unknown tags into the `unknown` field and use the first one as "language". So in this case, since there is no unknown tag, it'll simply generate `<pre class="language-c">`. I added tests to cover this.
EDIT(camelid): This description is out-of-date. Using `custom,class:language-c` will generate the output `<pre class="language-class:language-c">` as would be expected; it treats `class:language-c` as just the name of a language (similar to the langstring `c` or `js` or what have you) since it does not use the designed class syntax.
Finally, I added a parser for the codeblock attributes to make it much easier to maintain. It'll be pretty easy to extend.
As to why this syntax for adding attributes was picked: it's [Pandoc's syntax](https://pandoc.org/MANUAL.html#extension-fenced_code_attributes). Even if it seems clunkier in some cases, it's extensible, and most third-party Markdown renderers are smart enough to ignore Pandoc's brace-delimited attributes (from [this comment](https://github.com/rust-lang/rust/pull/110800#issuecomment-1522044456)).

Support mdBook preprocessors for TRPL in rustbook
`rust-lang/book` recently added two mdBook preprocessors. Enable `rustbook` to use those preprocessors for books where they are requested by the `book.toml` by adding the preprocessors as path dependencies, and ignoring them where they are not requested, i.e. by all the books other than TRPL at present.
