Track them via pending_flush_bits. Previously WFI was only tracked in flush_bits and WAIT_FOR_ME was emitted directly. This means that we don't emit WAIT_FOR_ME or WAIT_FOR_IDLE if there wasn't a cache flush or other write by the GPU. Also split up host writes from sysmem writes, as only the former require WFI/WAIT_FOR_ME. Along the way, I also realized that we were missing proper handling of transform feedback counter writes which require WAIT_MEM_WRITES. Plumb that through as well. And CmdDrawIndirectByteCountEXT needs a WAIT_FOR_ME as it does not wait for WFI internally. As an example of what this does, a typical barrier for transform feedback with srcAccess = VK_TRANSFORM_FEEDBACK_WRITE_COUNTER_BIT_EXT and dstAccess = VK_ACCESS_INDIRECT_COMMAND_READ_BIT used to emit on A650: - WAIT_FOR_IDLE and now we emit: - WAIT_MEM_WRITES - WAIT_FOR_ME So we've eliminated a useless WFI and added some necessary waits.
