i386: Fix k*shift* intrinsics [PR93673]
As mentioned in the PR, the intrinsics allow counts from 0 to 255, but
we actually reject values from 128 to 255. That is because QImode
CONST_INTs can be only -128 to 127. Fixed by using const_0_to_255_operand
and dropping the modes for the operands with those predicates
(the IL actually contains the CONST_INT which has VOIDmode).

* config/i386/sse.md (k<code><mode>): Drop mode from last operand and
use const_0_to_255_operand predicate instead of immediate_operand.
