Arm64: Support additional condition checks in select nodes (#78223)

Generating a FEQ or FNEU will generate an incorrect compare.

With the optimizer code fixed, it's not possible to generate a
test to trigger the code in codegen. However, the code as it is was
wrong. Given it's untested, it might be better to replace it with
some asserts?

I've added some general compare consume tests to ensure everything
is generated ok.
