10872: ide_db: build symbol index from crate def map r=Veykril a=jhgg
fixes#4842, #10764
Is this looking correct? 👀
- [x] build the symbol index based upon the CrateDefMap for the given crate in `crate_symbols`
- [x] make it multi threaded again, and figure out how to cache each moduleid's symbol index in salsa.
- [x] NavigationTarget for names in macros is wrong, need to figure out how to compute a text range in the original file id?
- [x] cleanup some duped code
- [x] collect macros from `ItemScope.declared_macros()` into symbol index.
- [x] store declared macros in `ItemScope` so we can figure out where macros were defined for the index.
- [x] do something about `SymbolIndex::for_files` - ideally it should use the new module symbol index stuff.
- [x] delete `source_file_to_file_symbols` & co...
- [x] figure out what to do about `library_symbols`
- [x] maybe... speed up the new `library_symbols` - the new impl is probably much slower, and definitely much less parallel. **deciding to do nothing here, we can optimize later if necerssary.**
- [x] fix failing test: `navigation_target::tests::test_nav_for_symbol` - notably the crate def map doesn't seem to find declarations inside function.
- [x] now a bunch of other tests are failing around auto_import & qualify_path handlers. :(
- [x] need to assoc items in traits and impls
