Malek Ben Slimane c1e7e4500c Thread Safety Analysis: Support passing scoped locks between functions with appropriate annotations (#110523) ...

This is helpful when multiple functions operate on the same
capabilities, but we still want to use scoped lockable types for
readability and exception safety.
- Introduce support for thread safety annotations on function parameters
  marked with the 'scoped_lockable' attribute.
- Add semantic checks for annotated function parameters, ensuring
  correct usage.
- Enhance the analysis to recognize and handle parameters annotated for
  thread safety, extending the scope of analysis to track these across
  function boundries.
- Verify that the underlying mutexes of function arguments match the
  expectations set by the annotations.

Limitation: This does not work when the attribute arguments are class
members, because attributes on function parameters are parsed
differently from attributes on functions.
