testsuite: Add test for already-fixed issue with _Pragma expansion [PR90400]
The PR was fixed by r12-5454. Since the fix was somewhat incidental,
although related, add a testcase from PR90400 too before closing it out.
gcc/testsuite/ChangeLog:
PR preprocessor/90400
* c-c++-common/cpp/pr90400.c: New test.
