[roll] Roll fuchsia [scenic] Optimize scenic_session_present tracing.
This CL contains optimizations for both "tracing on" and "tracing off"
scenarios.
Tracing on:
In cases where multiple Flatland clients are simultaneously presenting,
this CL combines multiple "instaflow" events into a single duration.
An additional win is to not put redundant args like "frame_number" onto
each flow even, instead only storing them once on the enclosing
duration.
Tracing off:
Many functions contain multiple trace events (flows, durations etc);
these can sum to a non-negligible cost, even when tracing is disabled.
cost. In such cases we can use `if (TRACE_CATEGORY_ENABLED("gfx"))`
to reduce the cost.
