[X86] X86FixupInstTunings - add VPERMILPDri -> VSHUFPDrri mapping

Similar to the original VPERMILPSri -> VSHUFPSrri mapping added in D143787, replacing VPERMILPDri -> VSHUFPDrri should never be any slower and saves an encoding byte.

The sibling VPERMILPDmi -> VPSHUFDmi mapping is trickier as we need the same shuffle mask in every lane (and it needs to be adjusted) - I haven't attempted that yet but we can investigate it in the future if there's interest.

Fixes #61060
