  [Clang] Fall back to DW_TAG_typedef for instantiation dependent template aliases (#90032)

Workaround for issue #89774 until it can be properly fixed.

When `-gtemplate-alias` is specified Clang emits a DW_TAG_template_alias
for template aliases. This patch avoids an assertion failure by falling
back to the `-gno-template-alias` (default) behaviour, emitting a
DW_TAG_typedef, if the alias is instantiation dependent.
