[X86] Cleanup CVTPD2PS schedule values

The znver1/znver2 schedules for CVTPD2PS were incorrectly double pumping the xmm-load variant instead of the ymm variants (znver1 only)

Also, the xmm-load variant was incorrectly using FP03 instead of just FP3

Confirmed by the AMD SoG 17h tables, Agner + uops.info

Another step towards removing a lot of unnecessary overrides from all the x86 scheduler models - these should hopefully be convertible into regular WriteCvtPD2I classes soon.
