CPU (A64): Add FP16/FP32 fast paths (F16C Intrinsics) for Fcvt_S, Fcvtl_V & Fcvtn_V Instructions. Now HardwareCapabilities uses CpuId. (#1650)

* net5.0

* CPU (A64): Add FP16/FP32 fast paths (F16C Intrinsics) for Fcvt_S, Fcvtl_V & Fcvtn_V Instructions. Switch to .NET 5.0.

Nits.

Tests performed successfully in both debug and release mode (for all instructions involved).

* Address comment.

* Update appveyor.yml

* Revert "Update appveyor.yml"

This reverts commit 27cdd59e8b.

* Remove Assembler CpuId.

* Update appveyor.yml
