fix: handle trait methods as inherent methods for trait-related types
Fixes#10677
When resolving methods for trait object types and placeholder types that are bounded by traits, we need to count the methods of the trait and its super traits as inherent methods. This matters because these trait methods have higher priority than the other traits' methods.
Relevant code in rustc: [`assemble_inherent_candidates_from_object()`](0631ea5d73/compiler/rustc_typeck/src/check/method/probe.rs (L783-L792)) for trait object types, [`assemble_inherent_candidates_from_param()`](0631ea5d73/compiler/rustc_typeck/src/check/method/probe.rs (L838-L847)) for placeholder types. Notice the second arg of `push_candidate()` is `is_inherent`.
Previously, annotations would only appear above the name of an item (function signature, struct declaration, etc).
Now, rust-analyzer can be configured to show annotations either above the name or above the whole item (including doc comments and attributes).
The name might need some improving.

fix: sort all bounds on trait object types
Fixes#13181#12793 allowed different ordering of trait bounds in trait object types but failed to account for the ordering of projection bounds. I opted for sorting all the bounds at once rather than splitting them into `SmallVec`s so it's easier to do the same thing for other bounds when we have them.
fix: Insert whitespaces into static & const bodies if they are expanded from macro on hover
Partially fixes#13143.
To resolve the other part we need to expand macros in unevaluated static & const bodies, and I'm not sure we want to. If for example it includes a call to `assert!()`, expanding it will lead to worse hover.
It seems that we've accidentally deleted the tests here couple of years
ago, and then fairly recently made a typo during refactor as well.
Reinstall tests, with coverage marks this time :-)
A Resolver *always* has a module scope at the end of its scope stack,
instead of encoding this as an invariant we can just lift this scope
out into a field, allowing us to skip going through the scope vec
indirection entirely.
