Consider optimizing more intrinsics that have move/copy semantics

[echesakov]

The idea of preferential using op1Reg for targetReg for move/copy semantic intrinsics as it done in #40124 should be extended to x86 and more intrinsics on arm64 as pointed out by @CarolEidt and @tannergooding and @kunalspathak

For example, on Arm64 these could be potentially optimized:

• Vector64/128.GetElement(0)
• AdvSimd.Extract(vec, 0)
• AdvSimd.ExtractVector64(upper, lower, 0)
• AdvSimd.ExtractVector128(upper, lower, 0)
