Added trace data for latch and release buffers

It's helpful to see the specific layer and frame number that is being
latched and released in SF to ensure we can trace where buffers go.

Additionally, added new traces to BBQ where it could be flushing buffers
or waiting until there's a free buffer

Test: perfetto trace
