Add AVX10.1 target_clones support

Add AVX10.1 target_clones support

Since AVX10 is the first major ISA introduced after AVX-512, we propose
to add target_clones support for it.

Although AVX10.1-256 won't cover 512-bit part of AVX512F, but since
it is only for priority but not for implication, it won't be an issue.

gcc/ChangeLog:

	* common/config/i386/i386-common.cc: Change Granite Rapids
	series CPU type to P_PROC_AVX10_1_512.
	* common/config/i386/i386-cpuinfo.h (enum feature_priority):
	Revise comment part. Add P_AVX10_1_256, P_AVX10_1_512,
	P_PROC_AVX10_1_512.
	* common/config/i386/i386-isas.h: Link to avx10.1-256, avx10.1-512.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/avx10_1-25.c: New test.
