libcpp: Fix ICE lexing invalid raw string in a deferred pragma [PR117118]
The PR shows that we ICE after lexing an invalid unterminated raw string,
because lex_raw_string() pops the main buffer unexpectedly. Resolve by
handling this case the same way as for other directives.
libcpp/ChangeLog:
PR preprocessor/117118
* lex.cc (lex_raw_string): Treat an unterminated raw string the same
way for a deferred pragma as is done for other directives.

* c-c++-common/raw-string-directive-3.c: New test.
* c-c++-common/raw-string-directive-4.c: New test.
