Karol Herbst 08229beb4e nir: rework and fix rotate lowering
No driver supports urol/uror on all bit sizes. Intel gen11+ only for 16
and 32 bit, Nvidia GV100+ only for 32 bit. Etnaviv can support it on 8,
16 and 32 bit.

Also turn the `lower` into a `has` option as only two drivers actually
support `uror` and `urol` at this momemt.

Fixes crashes with CL integer_rotate on iris and nouveau since we emit
urol for `rotate`.

v2: always lower 64 bit

Fixes: fe0965afa6 ("spirv: Don't use libclc for rotate")
