So far we were packing by hand unnormalized coordinates at the V3D41_TMU_CONFIG_PARAMETER_1 pack structure. To get this working we hardcoded V3D_VERSION to 41 at v3dv_uniforms, that works for v71 because the structure are the same. But that is somewhat ugly, and will not work if a new hw generation have a different structure. Additionally, we found that for v3d this will be also needed. So this commit adds a helper on the compiler. For now, and to simplify it also use just one method for both generations. This solves the problem of the same code needed on both v3d and v3dv. But the idea is that in the future we need a similar need, but the structure different on each generation, it would have used a similar approach to other generation dependent function calls (like v3d40_vir_emit_tex), having the implementation on a source file that can safely include the hw generation headers.
