Add fixups for incomplete in proc-macros
Partially implements https://github.com/rust-lang/rust-analyzer/issues/12777.
Added support for for loops and match statements.
I couldn't do paths like `crate::foo::` as I wasn't able to add `SyntheticTokens` to the end of `foo::`, they always ended up after `crate::`
This is my first contribution so please don't be shy about letting me know if I've done anything wrong!
fix: make `concat!` work with char
Fixes#12921
- I avoided making `unquote_str()` take char literals as well because it's depended on by another function `parse_string()` that's only supposed to take strings.
- Even with this patch, we don't output `\0` as `\u{0}` which #12921 pointed out ~~, but we're not actually responsible for serializing it but rowan is~~. They are functionally equivalent and I don't think it'd cause any confusion, but we *could* try escaping them before serialization (for reference, `rustc -Zunpretty=expanded`, which `cargo expand` uses under the hood, [makes use of `str::escape_default()`](3830ecaa8d/compiler/rustc_ast/src/util/literal.rs (L161)).
More methods and traits for `la_arena::ArenaMap`
Continue of #12931. Seems that I forgot some methods in the previous PR :(
I also changed `ArenaMap::insert` to return the old value, to match the map-like collection API of std. **So this is a breaking change.**

Don't switch workspace on vfs file changes from libraries
When r-a starts up, it starts switching the workspace before all vfs
events have been processed which causes us to switch workspace multiple
times until all vfs changes have been processed. This scales with the
size of the project and its dependencies. If workspace files from
dependencies as well as the sysroot get loaded, we shouldn't switch
the workspace as those have no impact on the project workspace.

feat: Only flycheck workspace that belongs to saved file
Supercedes https://github.com/rust-lang/rust-analyzer/pull/11038
There is still the problem that all the diagnostics are cleared, only clearing diagnostics of the relevant workspace isn't easily doable though I think, will have to dig into that
Add syntax fixup for while loops
Part of https://github.com/rust-lang/rust-analyzer/issues/12777
This is a first iteration to gather some feedback. In particular I'm not sure if the curly braces should be added here, but I couldn't get the test to work without them. Any hints welcome!
