[x86] regenerate complete test checks for sqrt{est}; NFC

The existing checks were trying to test both CPU-specific
codegen and generic codegen with explicit attributes for
the various sqrt estimate possibilities, but that was hard
to decipher and update (D69989).

Instead generate the complete results for various CPUs,
and that makes it clear which models have slow/fast sqrt
attributes along with all of the other potential diffs
(FMA, AVX2, scheduling).

Also, explicitly add the function attributes corresponding
to whether DAZ/FTZ denorm settings are expected.
