tu: use the stats framework

Browse Source 
This doesn't "go all the way", ideally we'd plumb stats into ir3
compiler and then reuse the generated code for GL. See
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33921 for an
example of that. But this is a step in the right direction by itself.
