Revert "x86/APX: drop AMX-TRANSPOSE promoted insns"

This reverts commit bafcf0823c1ae4c2201670225c9cf14ccf2abc67.

The patch (the removal) was done on the wrong assumption that
it was only the APX-promoted forms which would be dropped
because the APX spec was updated ahead of ISE and there was no
info that AMX-TRANSPOSE would be de-published at that time.
Given the current situation, since we will choose to disable
AMX-TRANSPOSE but not to remove the support in Binutils, we will
also not remove the APX support.
