tu: Rewrite visibility stream allocation

Browse source 
The mechanism implemented in the hardware to synchronize against Write
after Read hazards with the visibility stream for concurrent binning is
for BV and BR to keep track of the number of render passes they have
finished and BV waits until
BR_count >= BV_count - vis stream count. For example, if
there are two visibility streams and the user submits three
renderpasses, before starting renderpass #3 BV will wait for BR to
finish renderpass #1. It's assumed that renderpass #3 and #2 use
different visibility streams, so it's safe to start working on #3 once
 #2 is done.

This mechanism is assumed to work across renderpasses and even submits,
and the only way to reset the BR/BV counts is via
CP_RESET_CONTEXT_STATE which is only done by the kernel when
switching contexts. This vastly complicates things for Vulkan,
where we have no idea what order command buffers will be submitted. This
means that we have to defer emitting the actual pointers until
submission time and create patchpoints instead. This gets unfortunately
very complicated with SIMULTANEOUS_USE_BIT where we have to update the
patchpoints on the GPU.

I've taken the liberty of also deferring the allocation of the
visibility stream until submit time. This will help us later move to
per-queue visibility streams, which will be necessary for supporting
multiple simultaneous queues.
