Establish groups of resolve and unresolve operations that the a7xx hardware can then use to improve efficiency. Creating such groups enables continuation of command stream processing while these (un)resolves are in progress, as long as those latter operations don't depend on the grouped (un)resolves. To enable concurrent resolves and unresolves, corresponding fields on the RB_CCU_CNTL register have to be set appropriately. Resolve groups are tracked through a scoped struct that logs any pending resolve operation. Once the group is complete, the emit helper function will write out the CCU_END_RESOLVE_GROUP event to the command stream. The buffer ID field on the RB_BLIT_INFO register can be used to disperse different resolve operations across all available slots in the resolve engine. The 0x8 and 0x9 IDs are reserved for depth and stencil buffers, while the 0x0-0x7 range is used for color buffers. A simple incremented counter is used to assign IDs for all color buffers inside any resolve group. While it can occur for two color or depth/stencil buffers inside the same resolve group to have identical IDs, hardware doesn't seem to have a problem with handling that. Two TU_DEBUG options are provided, 'noconcurrentresolves' and 'noconcurrentunresolves` disable respective operations by adjusting the mode set through RB_CCU_CNTL.
