* Introduce SymbolBody representation (compact), from which the
body can be reconstructed, rendering body computation lazy
* Introduce SymbolBodyFactory for the creation of such instances,
ensuring that instances created from the same factory share
the same file content, allowing the in-memory and on-disk caches
to have a significantly smaller memory footprint
* Change type of "body" key in UnifiedSymbolRepresentation to use
SymbolBody instead of str
* Adjust all usages of the "body" key
instead of creating new low-level data structures.
This enables uniform handling of required conversions in our
higher-level Serena data structures
Fixes#432
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
