radv: fix set_output_usage_mask() with composite and 64-bit types
It previously used var->type instead of deref_instr->type and didn't
handle 64-bit outputs.
This fixes lots of transform feedback CTS tests involving transform
feedback and geometry shaders (mostly
dEQP-VK.transform_feedback.fuzz.random_geometry.*)
v2: fix writemask widening when comp != 0
v3: fix 64-bit variables when comp != 0, again
