c++: Fix ICE-on-invalid with broken attribute [PR93684]

We crash when parsing

  [[a::

because we see a CPP_SCOPE and then we're trying to consume a CPP_EOF
token.  So peek before consuming it.

PR c++/93684 - ICE-on-invalid with broken attribute.
* parser.c (cp_parser_std_attribute): Peek a token first before
consuming it.

* g++.dg/parse/attr4.C: New test.
