tu: Rewrite inline uniform implementation

Now we always push the inline uniforms, using an indirect CP_LOAD_STATE.
There is just enough space to be able to always push them if we expose
the minimum possible per-stage limits. This aligns us with Qualcomm and
removes the need to setup a uniform descriptor which will be
problematic.
