PR target/96307: Fix KASAN option checking.
- Disable kasan if target is unsupported and -fasan-shadow-offset= is not
given, no matter `--param asan-stack=1` is given or not.
- Moving KASAN option checking testcase to gcc.dg, those testcase could be
useful for all other target which not support asan.
- Verifed on riscv and x86.
