  [Clang] Recurse into parsing when using pack-indexing as a specifier (#119123)

Pack indexing type that introduces a scope, e.g. `T...[0]::value` would
be annotated as `annot_cxxscope`. This is something we didn't handle in
`ParseCastExpression`, causing it to mistakely fall through to the logic
for `raw_identifier`.

We should recurse into parsing the following specifiers for such cases.

Closes #119072
