Perfetto: Optimize proto usage

This bundles multiple events into the same higher-level message and adds
a string table implementation for frequently repeated strings,
on a per-thread basis; specifically the event name, category name,
and the name of its arguments.

Requires https://android-review.googlesource.com/c/platform/external/perfetto/+/755290
to roll into //third_party/perfetto before landing.
