Start introducing commands to setup BV. We need to run the initial register setup with both BR and BV enabled, and similarly we need to setup a bin preamble for BV. A few magic registers are BR-only and should be skipped when initializing BV. The VPC attribute carveout registers are a bit special because they must be initialized in BR and BV bin preambles, so they are pulled into a separate function. This commit also switches the "default" thread control from BR with concurrent binning disabled to BR with concurrent binning enabled. GMEM renderpasses now explicitly disable concurrent binning. This is necessary because switching from CB enabled to disabled and vice versa imposes a synchronization, and we want BV to be able to skip over compute dispatches, sysmem renderpasses, etc. to find the next binning pass. GMEM renderpasses re-enable concurrent binning at the end to keep the "default" thread control and avoid having to sprinkle THREAD_CONTROL(BR) around all the other Vulkan commands that can run outside of a renderpass (compute dispatch, blits, query pool operations, etc.).
