test: Remove gccbug_90348 test case

The test case no longer detects this specific issue for GCC versions
12.1+, as explained in the
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90348 thread and in this
compiler-explorer playground:
https://godbolt.org/z/Y48osrjM8

So remove the test case and update the -fstack-reuse=none cmake
docstring with the underlying affected GCC versions, and the bug URL.
