brw/opt: Don't call brw_opt_copy_propagation before brw_lower_load_reg 
On a 36c/72t Xeon system, performance of replaying
hogwarts_legacy.dx12vk-ultra.foz was improved 1.3% +/- 0.77% (n=10).

I picked MTL for the fossil-db results because it was the most negative.

shader-db:

All Intel platforms had fairly similar results. (Lunar Lake)
total instructions in shared programs: 16964217 -> 16964216 (<.01%)
instructions in affected programs: 51777 -> 51776 (<.01%)
helped: 20 / HURT: 27

total cycles in shared programs: 892934916 -> 893041912 (0.01%)
cycles in affected programs: 51245298 -> 51352294 (0.21%)
