freedreno/a3xx: parameterize ubo optimization

A3xx apparently has higher alignment requirements than later gens for
indirect const uploads. It also has fewer of them. Add compiler
parameters for both settings, and set accordingly for a3xx and a4xx+.
This fixes all the ubo test failures caused by this optimization.
