protos: Add support for counters in TrackEvent
Adds a generic way to describe counter tracks and supply counter values
in TrackEvents.
We support two types of counters: built-in (e.g. thread time,
instruction count) and custom user-specified. Counter values can be
provided in separate TrackEvents of TYPE_COUNTER, or attached to other
slice-type TrackEvents (i.e. at beginning/end of a slice).
Delta-encoding of counter values is also supported.
This will enable us to support TRACE_COUNTER macros in the client
library as well as experiment with more per-event counters in Chrome
(see crrev.com/c/1940179 for related discussion about the latter).
