Add `profile` calls to {Module,Function}::diagnostics

With this change the output `ra_prof` gives a better indication where
the time is spent. Example output:

```
  213ms - publish_diagnostics
      213ms - diagnostics
           70ms - Module::from_definition
               70ms - Module::from_file
          132ms - Module::diagnostics
               78ms - Function::diagnostics
                    0ms - body_with_source_map_query (1 calls)
                    2ms - trait_solve_query (1 calls)
                   76ms - ???
               15ms - Function::diagnostics
                    0ms - body_with_source_map_query (1 calls)
                   15ms - trait_solve_query (5 calls)
               38ms - Function::diagnostics (51 calls)
            8ms - parse_query (1 calls)
 ```
