i386: Deprecate -m[no-]avx10.1 and make -mno-avx10.1-512 to disable the whole AVX10.1
Based on the feedback we got, we would like to re-alias avx10.x to 512
bit in the future. This leaves the current avx10.1 alias to 256 bit
inconsistent. Since it has been there for GCC 14.1 and GCC 14.2,
we decide to deprecate avx10.1 alias. The current proposal is not
adding it back in the future, but it might change if necessary.
For -mno- options, it is confusing what it is disabling when it comes
to avx10. Since there is barely usage enabling AVX10 with 512 bit
then disabling it, we will only provide -mno-avx10.x options in the
future, disabling the whole AVX10.x. If someone really wants to disable
512 bit after enabling it, -mavx10.x-512 -mno-avx10.x -mavx10.x-256 is
the only way to do that since we also do not want to break the usual
expression on -m- options enabling everything mentioned.
However, for avx10.1, since we deprecated avx10.1, there is no reason
we should have -mno-avx10.1. Thus, we need to keep -mno-avx10.1-[256,512].
To avoid confusion, we will make -mno-avx10.1-512 to disable the
whole AVX10.1 set to match the future -mno-avx10.x.
