Introduce ShadeTraceLogger

This class unifies trace events related to the trace in a new track in perfetto.

This makes understanding what's going on much easier, as events are not lost in the middle of the main thread, but immediately visible and easy to parse.

This will be particurlarly helpful to debug cases of slow shade move between display from field traces.
