Optimize some SSE2 intrinsic importation and re-enable tests

[fiigii]

This PR

1. re-enables the hardware intrinsic tests that were disabled in Fix inconsistent Intel hardware intrinsic APIs #19949 and moves to template-based.
2. optimize some SSE2 intrinsic importation by removing unnecessary HW_Flag_BaseTypeFromFirstArg, which avoid calling into the expensive VM functions.

It would be nice if we could just move this to be templated.

[fiigii]

This test will be changed again after exposing 64-bit intrinsic in nested classes. Let’s move them later.

[tannergooding]

LGTM, but would like to see PopCnt moved to a templated test, if possible.

[fiigii]

Can we merge this?

[tannergooding]

It would be nice if @CarolEidt could give this a cursory glance as well.

[fiigii]

Thanks, I will move all the scalar intrinsic tests to the template after #20146 gets done.

@CarolEidt ping?
