historically zink has been bound to 4 gfx batches and then a separate compute batch
was added. this is not ideal for a number of reasons, the primary one being that if
an application performs 5 glFlush commands, the fifth one will force a gpu stall
this patch aims to do the following, all of which are necessarily done in the same patch
because they can't be added incrementally and still have the same function:
* rewrite batch tracking for resources/views/queries/descriptors/...
|originally this was done with a single uint32_t as a bitmask, but that becomes cumbersome
to track as batch counts increase, not to mention it becomes doubly-annoying
when factoring in separate compute batches with their own ids. zink_batch_usage gives
us separate tracking for gfx and compute batches along with a standardized api for
managing usage
* flatten batch objects to a gfx batch and a compute batch
|these are separate queues, so we can use an enum to choose between an array[2] of
all batch-related objects
* switch to monotonic batch ids with batch "states"
|with the flattened queues, we can just use monotonic uints to represent batch ids,
thus freeing us from constantly using bitfield operations here and also enabling
batch counts to scale dynamically by allocating/caching "states" that represent a batch
for a given queue
