Narrow _typeshed.ProfileFunction and _typeshed.TraceFunction by the event names they are documented to take

[jonathandung]

Changes the above definitions to the following:

# Objects suitable to be passed to sys.setprofile, threading.setprofile, and similar
ProfileFunction: TypeAlias = Callable[[FrameType, Literal["call", "return", "c_call", "c_return", "c_exception"], Any], object]

# Objects suitable to be passed to sys.settrace, threading.settrace, and similar
TraceFunction: TypeAlias = Callable[
    [FrameType, Literal["call", "line", "return", "exception", "opcode"], Any], TraceFunction | None
]

where the Literal's were originally typed as plain strings. This is from these python docs snippets for sys.settrace and sys.setprofile.
