This PR will fix some typos detected by [typos].
There are also some other typos in the function names, variable names, and file
names, which I leave as they are. I'm more certain that typos in comments
should be fixed.

fix: Fix incorrect type mismatch with `cfg_if!` and other macros in expression position
Fixes https://github.com/rust-lang/rust-analyzer/issues/12940
This is a bit of a hack, ideally `MacroStmts` would not exist at all after HIR lowering, but that requires changing how the lowering code works.
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)).
internal: Use ItemTree for variant, field and module attribute collection in attrs_query
Less parsing = very good, should speed up lang item collection as that basically probes attributes of all enum variants which currently triggers parsing
Not fond of how this is searching for the correct index, ideally we'd map between HIR and item tree Id here but I am not sure how, storing the item tree ids in the HIR version doesn't work due to the usage of `Trace`...
internal: Record all macro definitions in ItemScope
Fixes https://github.com/rust-lang/rust-analyzer/issues/12100
Doesn't resolve the shadowing issues though, fixing those is gonna be really tricky I believe unless we can come up with a nice scheme to "order" item tree items (using syntax ranges and file ids would be a pain and also a bad idea since that'll require us to potentially reparse files in collection).
