[AMDGPU][Attributor] Infer inreg attribute in `AMDGPUAttributor`
This patch introduces `AAAMDGPUUniformArgument` that can infer `inreg` function
argument attribute. The idea is, for a function argument, if the corresponding
call site arguments are always uniform, we can mark it as `inreg` thus pass it
via SGPR.
In addition, this AA is also able to propagate the inreg attribute if feasible.
