i386: Add PTA_AVX10_1_256 to PTA_DIAMONDRAPIDS
For -march= handling, PTA_AVX10_1 will not imply PTA_AVX10_1_256,
resulting in TARGET_AVX10_1 becoming true while TARGET_AVX10_1_256
false. Since we will check TARGET_AVX10_1_256 in GCC 15 for AVX512
feature enabling for AVX10, -march=diamondrapids will not enable
512 bit register and x/ymm16+.
Since AVX10 will get a further clean up in GCC 16 and will help
PTA_DIAMONDRAPIDS reusing PTA_GRANITERAPIDS_D, the imply would become
obvious again, I plan not to add the testcase but just to fix the issue
in GCC 15.
gcc/ChangeLog:
* config/i386/i386.h (PTA_DIAMONDRAPIDS): Add PTA_AVX10_1_256.
