Implement `std::marker::Tuple`, use it in `extern "rust-call"` and `Fn`-family traits
Implements rust-lang/compiler-team#537
I made a few opinionated decisions in this implementation, specifically:
1. Enforcing `extern "rust-call"` on fn items during wfcheck,
2. Enforcing this for all functions (not just ones that have bodies),
3. Gating this `Tuple` marker trait behind its own feature, instead of grouping it into (e.g.) `unboxed_closures`.
Still needing to be done:
1. Enforce that `extern "rust-call"` `fn`-ptrs are well-formed only if they have 1/2 args and the second one implements `Tuple`. (Doing this would fix ICE in #66696.)
2. Deny all explicit/user `impl`s of the `Tuple` trait, kinda like `Sized`.
3. Fixing `Tuple` trait built-in impl for chalk, so that chalkification tests are un-broken.
Open questions:
1. Does this need t-lang or t-libs signoff?

rustdoc: add hash to filename of toolchain files
All static files used by rustdoc are now stored in static.files/ and their filenames include a hash of their contents. Their filenames no longer include the contents of the --resource-suffix flag. This clarifies caching semantics. Anything in static.files can use Cache-Control: immutable because any updates will show up as a new URL.
Invocation-specific files like crates-NN.js, search-index-NN.js, and sidebar-items-NN.js still get the resource suffix.
This has a useful side effect: once toolchain files aren't affected by resource suffix, it will become possible for docs.rs to include crate version in the resource suffix. That should fix a caching issue with `/latest/` URLs: https://github.com/rust-lang/docs.rs/issues/1593. My goal is that it should be safe to serve all rustdoc JS, CSS, and fonts with infinite caching headers, even when new versions of a crate are uploaded in the same place as old versions.
The --disable-minification flag is removed because it would vary the output of static files based on invocation flags. Instead, for rustdoc development purposes it's preferable to symlink static files to a non-minified copy for quick iteration.

Auto merge of #103691 - michaelwoerister:consistent-slice-and-str-cpp-like-debuginfo-names, r=wesleywiser
[debuginfo] Make cpp-like debuginfo type names for slices and str consistent.
Before this PR, the compiler would emit the debuginfo name `slice$<T>` for all kinds of slices, regardless of whether they are behind a reference or not and regardless of the kind of reference. As a consequence, the types `Foo<&[T]>`, `Foo<[T]>`, and `Foo<&mut [T]>` would end up with the same type name `Foo<slice$<T> >` in debuginfo, making it impossible to disambiguate between them by name. Similarly, `&str` would get the name `str` in debuginfo, so the debuginfo name for `Foo<str>` and `Foo<&str>` would be the same. In contrast, `*const [bool]` and `*mut [bool]` would be `ptr_const$<slice$<bool> >` and `ptr_mut$<slice$<bool> >`, i.e. the encoding does not lose information about the type.
This PR removes all special handling for slices and `str`. The types `&[bool]`, `&mut [bool]`, and `&str` thus get the names `ref$<slice2$<bool> >`, `ref_mut$<slice2$<bool> >`, and `ref$<str$>` respectively -- as one would expect.
The new special name for slices is `slice2$` to differentiate it from the previous name `slice$`, which has different semantics. The same is true for `str` and `str$`. This kind of versioning already has a precedent with the case of `enum$` and `enum2$` and hopefully will make it easier to transition existing consumers of these names.
As you can see, before the PR many types would end up with the same name, making it impossible to distinguish between them in NatVis or other places where types are matched or looked up by name. The DWARF version of names is not changed.

This flag was added by ```@eddyb``` in 6b3cc0b8c8094407a3b5ea75f946c682d6d0142a, and it's likely that it was made redundant due to subsequent restructuring of the compiler.

Spans are independent of the body being borrow-checked, so they don't
need remapping when promoting type-tests and they yield more specific
error spans inside bodies of closures/inline consts.

This made it impossible to check how rustc would behave when a flag requiring an argument was passed without the argument, because the argument would become `-L`.
This PR fixes that by adding the `-L path/to/aux` before the arguments defined in compile-flags, at least for UI tests. Other test suites might either be fixed as well by this change, or still present the old behavior (`-L` is now always passed before, but other tests suites might add additional flags after the custom ones).
