Add keyboard handling to the theme picker menu
This PR is mostly designed to bring the theme picker closer to feature parity with the menu bar from docs.rs. Though the rustdoc theme picker is technically already usable from the keyboard, it's really weird that arrow keys work on some of the menus, but not all of them, in the exact same page.
Change as_str → to_string in proc_macro::Ident::span() docs
There is no `as_str` function on Ident any more.
Also change it to an intra doc link while we're at it.
Move Vec UI tests to unit tests when possible
Helps with #76268.
I'm moving the tests using `Vec` or `VecDeque`.

Bump actions/checkout to version 2
This was recommended by GitHub Support to try reducing the things that could've caused #78743. I checked the changelog and there should be no practical impact for us (we already set an explicit fetch-depth).

Provide diagnostic suggestion in ExprUseVisitor Delegate
The [Delegate trait](981346fc07/compiler/rustc_typeck/src/expr_use_visitor.rs (L28-L38)) currently use `PlaceWithHirId` which is composed of Hir `Place` and the
corresponding expression id.
Even though this is an accurate way of expressing how a Place is used,
it can cause confusion during diagnostics.
Eg:
```
let arr : [String; 5];
let [a, ...] = arr;
^^^ E1 ^^^ = ^^E2^^
```
Here `arr` is moved because of the binding created E1. However, when we
point to E1 in diagnostics with the message `arr` was moved, it can be
confusing. Rather we would like to report E2 to the user.

Refactorings in preparation for const value trees
cc #72396
This PR changes the `Scalar::Bits { data: u128, size: u8 }` variant to `Scalar::Bits(ScalarInt)` where `ScalarInt` contains the same information, but is `repr(packed)`. The reason for using a packed struct is to allow enum variant packing to keep the original size of `Scalar` instead of adding another word to its size due to padding.
Other than that the PR just gets rid of all the inspection of the internal fields of `Scalar::Bits` which were frankly scary. These fields have invariants that we need to uphold and we can't do that without making the fields private.

Use reparsed `TokenStream` if we captured any inner attributes
Fixes#78675
We now bail out of `prepend_attrs` if we ended up capturing any inner
attributes (which can happen in several places, due to token capturing
for `macro_rules!` arguments.
Fix panic in bootstrap for non-workspace path dependencies.
If you add a `path` dependency to a `Cargo.toml` that is located outside of the workspace, then the `in_tree_crates` function can panic because it finds a path dependency that is not defined (since it uses `cargo metadata --no-deps`). This fixes it by skipping over those entries, which are usually not things you select on the command-line.
Fixes#78617
Suggest library/std when running all stage 0 tests
r? ``@Mark-Simulacrum``
cc ``@ijackson``
For context, this came out of a discord conversation where ``@ijackson`` was running `test --stage 1` when they were only adding doc-tests to the standard library.
