c++: Fix template parm ICE [PR 98297]

I think this is nonsense code, we seem to be naming an instantiation
of a template template parm.  But this fixes the ICE.  Perhaps we
should diagnose the issue earlier?

gcc/cp/
* parser.c (cp_parser_elaborated_type_specifier): Test
BOUND_TEMPLATE_TEMPLATE_PARM before checking for instantiation.
gcc/testsuite/
* g++.dg/template/pr98297.C: New.
