testsuite: Adjust AVX10.2 check_effective_target

Since Binutils haven't fully merged all AVX10.2 insts, only testing
one inst/intrin in AVX10.2 is never sufficient for check_effective_target.
Like APX_F, use inline asm to do the target check.

gcc/testsuite/ChangeLog:

	PR target/117301
	* lib/target-supports.exp (check_effective_target_avx10_2):
	Use inline asm instead of intrin for check_effective_target.
	(check_effective_target_avx10_2_512): Ditto.
