Introduce separate helper functions to set the blendfactor bits. Lima uses bits 0-2 for the type, bit 3 sets the inverted function and bit 4 is set if alpha is used. alpha_src_factor and alpha_dst_factor don't need the alpha bit, so they are masked with 0xf. There is only place for 4 bits anyway. If alpha_src_factor is PIPE_BLENDFACTOR_SRC_ALPHA_SATURATE, we need to change it to PIPE_BLENDFACTOR_ONE first. This is exactly what the blob does and we pass all dEQP-GLES2.functional.fragment_ops.blend.* tests now. Better than the blob btw...
