Auto merge of #17905 - ChayimFriedman2:edition-dependent-raw-keyword, r=Veykril

fix: Properly account for editions in names

This PR touches a lot of parts. But the main changes are changing `hir_expand::Name` to be raw edition-dependently and only when necessary (unrelated to how the user originally wrote the identifier), and changing `is_keyword()` and `is_raw_identifier()` to be edition-aware (this was done in #17896, but the FIXMEs were fixed here).

It is possible that I missed some cases, but most IDE parts should properly escape (or not escape) identifiers now.

The rules of thumb are:

 - If we show the identifier to the user, its rawness should be determined by the edition of the edited crate. This is nice for IDE features, but really important for changes we insert to the source code.
 - For tests, I chose `Edition::CURRENT` (so we only have to (maybe) update tests when an edition becomes stable, to avoid churn).
 - For debugging tools (helper methods and logs), I used `Edition::LATEST`.

Reviewing notes:

This is a really big PR but most of it is mechanical translation. I changed `Name` displayers to require an edition, and followed the compiler errors. Most methods just propagate the edition requirement. The interesting cases are mostly in `ide-assists`, as sometimes the correct crate to fetch the edition from requires awareness (there may be two). `ide-completions` and `ide-diagnostics` were solved pretty easily by introducing an edition field to their context. `ide` contains many features, for most of them it was propagated to the top level function and there the edition was fetched based on the file.

I also fixed all FIXMEs from #17896. Some required introducing an edition parameter (usually not for many methods after the changes to `Name`), some were changed to a new method `is_any_identifier()` because they really want any possible keyword.

Fixes #17895.
Fixes #17774.
