A cooperative matrix conversion operation was represented in NIR by the cmat_unary_op intrinsic with an nir_alu_op as extra parameter, that was already lowered to a specific conversion operation based on the matrix types. Instead of that, add a new intrinsic `cmat_convert` that is specific for that conversion. In addition to the src/dst matrix descriptions already available, also include the signedness information in the intrinsic (reuse nir_cmat_signed for that). This is needed because different Convert operations define different interpretations for integers, regardless their original type. In this patch, both radv and intel were changed to use the same logic that was previously used to pick the lowered ALU op. This change will help represent cmat conversions involving BFloat16, because it avoids having to create new NIR ALU ops for all the combinations involving BFloat16.
