languages: Improve semantic token highlighting for parameters and Python (#52130)
## Context

Zed's semantic token highlighting does not cover all token types
returned by language servers, so the highlighting looks fairly primitive
compared with tree-sitter highlighting, especially for Python language
servers. This PR adds some global and Python-specific rules for better
highlighting.

I need to admit that the built-in Python language servers currently have
weak semantic highlighting implementations. Pylance, the closed-source
Python language server from Microsoft, provides the best highlighting
for now, but I think ty will do better, even though it still has a long
way to go.
## How to Review

Basically, this is a rule-adding change. Some rules are made global, and
some are made Python-specific.
