gallium/aux: Add GPU tracepoint mechanism

This adds a mechanism, loosely inspired by the linux kernel's tracepoint
mechanism, to declare and emit tracepoints.  A driver provided callback
is used to emit cmdstream to capture timestamps on the GPU, which are
used to later "render" the emitted tracepoints.
