Merge #6172
6172: Add qualify path assist r=matklad a=Veykril This implements a `qualify_path` assist which works quite similar to the `auto_import` assist but instead of adding imports to the file it well, qualifies the path. This PR also moves out the `AutoImportAssets` struct and functions from `auto_import` into a utils submodule as most of this is now shared between `auto_import` and `qualify_path`. Changes made to `AutoImportAssets` are solely in its `search_for_imports` function which now takes a prefixed parameter to discern between using `find_use_path_prefixed` and `find_use_path` as the former is the required behavior by `auto_import` and the latter by this assist. For missing imported traits instead of importing this will qualify the path with a trait cast as in: ```rust test_mod::TestStruct::TEST_CONST<|> ``` becomes ```rust <test_mod::TestStruct as test_mod::TestTrait>::TEST_CONST ``` and for trait methods ideally it would do the following: ```rust let test_struct = test_mod::TestStruct {}; test_struct.test_meth<|>od() ``` becomes ```rust let test_struct = test_mod::TestStruct {}; test_mod::TestTrait::test_method(&test_struct) ``` Fixes #4124.
