  Fix Issue 22325 - ReplaceType fails on templated type instantiated with
void-returning function

  Previously, when recursing into a type's template arguments,
  ReplaceTypeUnless would mistakenly attempt to evaluate a template alias
  parameter as an expression. In cases where the alias parameter was not a
  valid expression or could not be evaluated at compile time, this caused
  a compilation failure; in other cases, it caused ReplaceTypeUnless to
  give an incorrect result.

  This change makes ReplaceTypeUnless correctly treat template alias
  parameters as aliases.
