rustdoc-json-types: Clean up derives.
Closes#96189
Everything is `Clone, Debug, PartialEq, Eq, Hash, Serialize, Deserialize` except `Crate` and `Item` which arn't `Hash`, as they have `HashMap`'s. See linked issue for reasoning.

Remove most box syntax from librustdoc
This is the second attempt after the librustdoc specific changes have been reverted from #87781 in #89134, due to a minor, but exant regression caused by the changes. ~~There have been some changes to librustdoc in the past and maybe thanks to them there is no regression any more. If there is still a regression, one can investigate further and maybe find ways to fix the regressions. Thus, i request a perf run.~~ Edit: turns out there is still a regression, but it's caused only by a subset of the changes. So I've changed this PR to only contains the changes that don't cause any performance regressions, keeping the regression causing changes for a later PR.
Configure nightly branch name in `stage0.json`
The beta version number detection code relies on git to know how many merge commits were made since we branched off, and in doing so hardcodes `master` as the default branch name. This works for rust-lang/rust, but is problematic for forks that use a different default branch name (in Ferrocene we use `main` instead).
This PR changes the code to instead load the default branch name from `src/stage0.json`. `bump-stage0` has also been updated to remove the need to update it every time a new field is added to `stage0.json`.
interpret: refactor projection handling code
Moves our projection handling code into a common file, and avoids the use of a
general mplace-based fallback function by have more specialized implementations.
mplace_index (and the other slice-related functions) could be more efficient by
copy-pasting the body of operand_index. Or we could do some trait magic to share
the code between them. But for now this is probably fine.
This is the common part of https://github.com/rust-lang/rust/pull/99013 and https://github.com/rust-lang/rust/pull/99097. I am seeing some strange perf results so this probably should be its own change so we know which diff caused which perf changes...

I just realized I overwrote these two commits in https://github.com/rust-lang/rust/pull/99055 when force pushing to fix the stdout output...
r? `@Dylan-DPC`
Fix last `let_chains` blocker
In order to forbid things like `let x = (let y = 1);` or `if let a = 1 && { let x = let y = 1; } {}`, the parser **HAS** to know the context of `let`.
This context thing is not a surprise in the parser because you can see **a lot** of ad hoc fixes mixing parsing logic with validation logic creating code that looks more like spaghetti with tomato sauce.
To make things even greater, a new ad hoc fix was added to only allow `let`s in a valid `let_chains` context by checking the previously processed token. This was the only solution I could think of and believe me, I thought about it for a long time 👍
In the long term, it should be preferable to segregate different responsibilities or create a more robust and cleaner parser framework.
