[graphite] Introduce DispatchGroup and DispatchGroup::Builder
DispatchGroup represents a unit of sequentially executed compute
dispatches which share resources. Each dispatch is an invocation of a
ComputeStep instance over a common draw operation (represented by
common DrawParams).
A DispatchGroup is intended as the new building block for a ComputeTask.
It is the compute analog of a DrawPass, and handles pipeline creation,
resource tracking, and interacts with command encoding in a similar way.
ComputeSteps can be accummulated into a DispatchGroup using a
DispatchGroup::Builder which in particular handles the buffer allocation
and sharing among individual dispatches, using the resource layouts
described by the ComputeSteps.
