Fixing the InstructionSetDesc implications (#86486)

Fixing the InstructionSetDesc implications (#86486)

* Fixing the InstructionSetDesc implications

* Adding more NAOT smoke tests covering the missed instruction sets

* Simplify the HasInstructionSet(Avx512F) check in compSetProcessor

* Fixing the NAOT smoke tests

* Fixing some stale comments

* Fixing build failure

* Ensure the X86Serialize test lambda returns a bool

* Fixing build failure

* Ensure AVX2 isn't opportunistically supported and that dynamic checks work correctly for Vector128/256/512.IsHardwareAccelerated

* Ensure Avx512Vbmi has [Intrinsic] on the right members

* Fix the secondary isIsaSupported check to be properly opportunistic for NAOT

* Ensure vpermb is covered

* Allow opportunistic AvxVnni when Avx2 is opted into

* Don't expect opportunistic Avx2 or AvxVnni in the smoke tests

* Ensure Avx2.X64 checks ExpectedAvx2, not ExpectedAvx

* Change the filter the AVX512 NAOT smoke test on OSX

* Updating the CPUID test to cover new ISAs and correctly validate the hierarchy

* Add two more NAOT smoke tests which cover explicit ISA exclusion

* Add additional CpuId validation covering R2R scenarios using various ISA opt-in

* Ensure new R2R tests actually use R2R

* Don't try to expose an invalid --instruction-set combination

* Ensure xarch r2r tests only run on xarch

* Don't compare manufacturer name of CPUID 0x00000000 to 0x80000000

* Filter out the CPUID test on Mono and account for AVX-512 being unsupported on MacOS
