[ty] Use bitflags for resolved client capabilities

[dhruvmanila]

Summary

This PR updates the ResolvedClientCapabilities to be represented as bitflags. This allows us to remove the Arc as the type becomes copy.

Additionally, this PR also fixed the goto definition and declaration code to use the textDocument.definition.linkSupport and textDocument.declaration.linkSupport client capability.

This PR also removes the unused client capabilities which are code_action_deferred_edit_resolution, apply_edit, and document_changes which are all related to auto-fix ability.
