radv: save the bound pipeline pointers into the trace BO

When a GPU hang is detected in radv_gpu_hang_occured() we know
which command buffer is faulty but the bound pipelines might
have been updated during the execution.

The pointers to the radv_pipeline objects are emitted just
after the second trace ID, that way it would be easy to dump
the active shaders at the moment of the hang.
