RFR: 8317763: Follow-up to AVX512 intrinsics for Arrays.sort() PR [v3]

[Srinivas Vamsi Parasa]

> The goal of this PR is to address the follow-up comments to the SIMD accelerated sort PR (#14227) which implemented AVX512 intrinsics for Arrays.sort() methods.
> The proposed changes are:
> 
> 1) Restriction of the AVX512 sort acceleration to only Intel CPUs. A performance regression (due to micro-architectural differences) was reported for AMD Zen4 CPUs in the comments section of PR.
> 2) Addressing the build failure due to a bug in GCC 12 (which was fixed in version 12.3.1). The details of the bug are at: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105593
> 3) Minor changes in Javadoc strings
