Auto merge of #66279 - cjgillot:hashstable, r=Zoxc
Use proc-macro to derive HashStable everywhere Hello, A second proc-macro is added to derive HashStable for crates librustc depends on. This proc-macro `HashStable_Generic` (to bikeshed) allows to decouple code and strip much of librustc's boilerplate. Still, two implementations `Span` and `TokenKind` require to be placed in librustc. The latter only depends on the `bug` macro. Advise welcome on how to sever that link. A trait `StableHasingContextLike` has been introduced at each crate root, in order to handle those implementations which require librustc's very `StableHashingContext`. This overall effort allowed to remove the `impl_stable_hash_for` macro. Each commit passes the `x.py check`. I still have to double check there was no change in the implementation.
