2887: Initial auto import action implementation r=matklad a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/2180
Adds an auto import action implementation.
This implementation is not ideal and has a few limitations:
* The import search functionality should be moved into a separate crate accessible from ra_assists.
This requires a lot of changes and a preliminary design.
Currently the functionality is provided as a trait impl, more on that here: https://github.com/rust-analyzer/rust-analyzer/issues/2180#issuecomment-575690942
* Due to the design desicion from the previous item, no doctests are run for the new aciton (look for a new FIXME in the PR)
* For the same reason, I have to create the mock trait implementaion to test the assist
* Ideally, I think we should have this feature as a diagnostics (that detects an absense of an import) that has a corresponding quickfix action that gets evaluated on demand.
Curretly we perform the import search every time we resolve the import which looks suboptimal.
This requires `classify_name_ref` to be moved from ra_ide, so not done currently.
A few improvements to the imports mechanism to be considered later:
* Constants like `ra_syntax::SyntaxKind::NAME` are not imported, because they are not present in the database
* Method usages are not imported, they are found in the database, but `find_use_path` does not return any import paths for them
* Some import paths returned by the `find_use_path` method end up in `core::` or `alloc::` instead of `std:`, for example: `core::fmt::Debug` instead of `std::fmt::Debug`.
This is not an error techically, but still looks weird.
* No detection of cases where a trait should be imported in order to be able to call a method
* Improve `auto_import_text_edit` functionality: refactor it and move away from the place it is now, add better logic for merging the new import with already existing imports

2899: Provide more runners for potential tests r=matklad a=SomeoneToIgnore
Based on the https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Runners.20for.20custom.20test.20annotations discussion.
Adds a test runner for every method that has an annotation that contains `test` word in it, allowing to run tests annotated with custom testing annotations such as `#[tokio::test]`, `#[test_case(...)]` and others at costs of potentially emitting some false-positives.

2837: Accidentally quadratic r=matklad a=matklad
Our syntax highlighting is accdentally quadratic. Current state of the PR fixes it in a pretty crude way, looks like for the proper fix we need to redo how source-analyzer works.
**NB:** don't be scared by diff stats, that's mostly a test-data file

2772: Actually test references r=kjeremy a=kjeremy
This will be a little more work when `ReferenceSearchResults` change but I think it's easier to maintain in the end. It also follows a similar pattern to navigation targets and call hierarchy.

Let's be always explicit whether we create a library (i.e., an immutable
dependency) or a local `SourceRoot`, since it can have a large impact on
the validation performance in salsa. (we found it the hard way recently,
where the `Default` instance made it quite tricky to spot a bug)

When processing a change with added libraries, we used
`Default::default` for `SourceRoot` which sets `is_library` to false.
Since we use `is_library` to decide whether to use low or high
durability, I believe that this caused us to mark many library
dependencies as having low durability and thus increased the size of the
graph that salsa needed to verify on every change.
Based on my initial tests this speeds up the `CrateDefMapQuery` on
rust-analyzer from about ~64ms to ~14ms and reduces the number of
validations for the query from over 60k to about 7k.

This change:
- introduces `compute_crate_def_map` query and renames
`CrateDefMap::crate_def_map_query` for consistency,
- annotates `crate_def_map` as `salsa::transparent` and adds a
top-level `crate_def_map` wrapper function around that starts the
profiler and immediately calls into `compute_crate_def_map` query.
This allows us to better understand where we spent the time, in
particular, how much is spent in the recomputaiton and how much in
salsa.
Example output (where we don't actually re-compute anything, but the
query still takes a non-trivial amount of time):
```
211ms - handle_inlay_hints
150ms - get_inlay_hints
150ms - SourceAnalyzer::new
65ms - def_with_body_from_child_node
65ms - analyze_container
65ms - analyze_container
65ms - Module::from_definition
65ms - Module::from_file
65ms - crate_def_map
1ms - parse_macro_query (6 calls)
0ms - raw_items_query (1 calls)
64ms - ???

2667: Visibility r=matklad a=flodiebold
This adds the infrastructure for handling visibility (for fields and methods, not in name resolution) in the HIR and code model, and as a first application hides struct fields from completions if they're not visible from the current module. (We might want to relax this again later, but I think it's ok for now?)
