feat(css_parser): CSS Parser pseudo element selector #268

[denbezrukov]

Summary

• Improved error recovery and diagnostics for pseudo-class selectors. See snapshots.
• Added test cases to ensure correct handling of a closing token within selector context, particularly for space combinators, e.g., :host-context(h1) .div {}.
• Introduced eat_or_recover_selector_function_close_token, which attempts to consume a ) token; if unsuccessful, it recovers by consuming all tokens as bogus.
• Introduced recover_selector_function_parameter to handle invalid parameters by consuming all tokens until ).
• Noted code duplication across various selector kinds in checking identifiers and closing tokens. Suggest extracting common logic into a separate PR for better maintainability.

Test Plan

cargo test

I've changed a way how we recover if we don't find a close token.
I think that it's okey to consume all tokens until we find a )or a }.
See snapshots for examples.

It covers a case when we have only a double column token: :
