radv: vkCmdTraceRaysIndirect2KHR

Browse Source 
This changes the trace rays logic to always use
VkTraceRaysIndirectCommand2KHR and implements
vkCmdTraceRaysIndirect2KHR. I renamed the
load_sbt_amd to sbt_base_amd and moved the SBT
load lowering from ACO to NIR.

Note that we can not just upload one pointer to
all the trace parameters because that would
be incompatible with traceRaysIndirect.
