Add two missing validations for Required and NotRequired type qualifiers:

Reject their use outside of TypedDict class bodies (e.g. in regular classes, at module level, or in function bodies). Also reject ReadOnly outside TypedDict since it has the same constraint.
Reject nested usage like Required[Required[int]], NotRequired[NotRequired[int]], or Required[NotRequired[int]].
