pan/va: Fix nir_op_pack_uvec4_to_uint

Browse source 
We don't have a generic v4i8 on Valhall, we have to lower it to two
v2i8. Fortunately, bi_make_vec_to() hides the Bifrost/Valhall
differences, so use that for nir_op_pack_uvec4_to_uint.

Fixes: 934b0f1add ("pan/bi: Respect swizzles for more vector ops")
