[Mono] Enable generating SIMD intrinsics for System.Numerics.Vector on Arm64 (#65486)

* Enable SIMD intrinsics for System.Numerics.Vector on Arm64

* Minor adjustment

* Use the correct op code for BitwiseAnd, BitwiseOr and Xor

* Check if vector element type is a primitive type or not

* Remove dead code and fix constant formet

* Add type checks for each method and refactor

* Remove extra condition check

* Loose the type check for vector creation methods

* Remove type checks for Create* functions

* Remove some of the type checks
