This patch replace member accesses to declaration references during template
instantiation if the context is the unevaluated context and the class does not
contain the declaration.

The replacement fixes the issue #58674. Unlike previous fixes such as D143840 <https://reviews.llvm.org/D143840>,
it checks the membership during instantiation rather than right after parsing,
so the check is more accurate and efficient.

This patch also includes cases that previous fixes had once failed on.
