c: Allow $@` in GNU23/GNU2Y raw string delimiters [PR110343]
Aaron mentioned in the PR that late in C23 N3124 was adopted and
$@` are now part of basic character set. The paper has been implemented
in GCC from what I can see, but we should allow for GNU23/2Y $@` in
raw string delimiters as well, like they are allowed for C++26, because
the delimiters can contain anything from basic character set but space,
()\, tab, form-feed, newline and backspace.

* lex.cc (lex_raw_string): For C allow $@` in raw string delimiters
if CPP_OPTION (pfile, low_ucns) i.e. for C23 and later.
* gcc.dg/raw-string-1.c: New test.
