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.
