libcpp: Fix up raw string literal parsing error-recovery [PR96323]

For (invalid) newline inside of the raw string literal delimiter, doing
continue means we skip the needed processing of newlines.  Instead of
duplicating that, this patch just doesn't continue for those.

PR preprocessor/96323
* lex.c (lex_raw_string): For c == '\n' don't continue after
reporting
an prefix delimiter error.

* c-c++-common/cpp/pr96323.c: New test.

gcc11-pr96323.patch

Untested fix.  I think the easiest is to avoid the continue for newline and do
the usual new-line processing in there.

Oh, an excessive copy-paste.
