  [Clang] Treat default template argument as constant expressions (#107073)

We only check that a default argument is a converted constant expression
when using the default argument.

However, when parsing a default argument, we need to make sure to parse
it as a constant expression such as not ODR-use variables. (otherwise,
we would try to capture default template arguments of generic lambdas)

Fixes #107048
