  Fix consteval crash when transforming 'this' expressions

When reaching the end of a function body, we need to ensure that the
ExitFunctionBodyRAII object is destroyed before we pop the declaration context
for the function. Exiting the function body causes us to handle immediate
invocations, which involves template transformations that need to know the
correct type for this.

This addresses PR48235.
