Implement VCNT instruction (#1963)
* Implement VCNT based on AArch64 CNT

Add tests

* Update PTC version

* Address LDj's comments

* Explicit size in encoding
* Tighter tests
* Replace SoftFallback with IR helper

Co-authored-by: LDj3SNuD <35856442+LDj3SNuD@users.noreply.github.com>

* Reduce one BitwiseAnd from IR fallback

Based on popcount64b from https://en.wikipedia.org/wiki/Hamming_weight#Efficient_implementation

* Rename parameter and add assert
