anv/apply_pipeline_layout: Lower UBO loads in the early pass

We're about to enable bindless UBOs via A64 memory access like we do for
SSBOs.  In order to prevent 100% of UBOs from hitting that path, we
enable them in the early lowering.  This way we'll still get binding
table-based UBO access for any non-bindless ones.  In particular, we
need this for UBO pushing to work.
