Adds tests for name resolution for each language and fixes the name resolution where tests have failed.
Also:
Extends python tests to cover ty
Extends skipping conditions for several LS (but only when not in CI)
Better test output in CI
Removed a wrong python test (started failing for ty and should have failed for pyright too)
such that FindReferencingSymbolsTool is now also implemented without a direct reference
to the language server
All references to Component.language_server have been removed
adding all necessary related functionality:
* Handling of ignored files
* Enumeration of source files
Functions removed from SolidLanguageServer:
* index_repository
* request_parsed_files
* search_files_for_pattern
Implement SearchForPatternTool without language server
