  [clang] Fixed predefined expressions after lambda parameters (#211811)

After the parameter declaration of a lambda expression, `Sema` enters
the declaration context of the lambda call operator (in
`ActOnLambdaClosureParameters`), so the lambda specifiers and the
trailing return type are analyzed within that context. Because of this,
predefined expressions such as `__func__` resolve to the lambda call
operator, and not to the possibly enclosing function. (issue #122657)

Added a member to `LambdaScopeInfo` to mark whether or not the compound
statement of the lambda expression has been entered, to be used when
resolving a `PredefinedExpr`
