Reland "[VM] Begin supporting Perfetto file recorder"

Browse source 
This is a reland of commit 7424295ce9

The differences between this reland and the original CL are: now the
Perfetto file recorder does not get built in PRODUCT builds, and it does
not get built unless the SUPPORT_PERFETTO macro is defined.

TEST=Recorded traces with the Perfetto file recorder and explored them
in Perfetto's trace viewer, CI

Original change's description:
> [VM] Begin supporting Perfetto file recorder
>
> This CL adds the `TimelineEventPerfettoFileRecorder` class, which is a
> timeline recorder that writes a trace to file in Perfetto's proto
> format. This CL supports the recording of all types of timeline events
> except flow events. Support for flow events will be added in a future
> CL.
>
> TEST=Recorded traces with the Perfetto file recorder and explored them
> in Perfetto's trace viewer, CI

// NOTE: Full TrackEvent support in the client lib and chrome is WIP, thus these
// protos are still subject to change. Don't depend on them staying as they are.
// Trace events emitted by client instrumentation library (TRACE_EVENT macros),
// which describe activity on a track, such as a thread or asynchronous event
// track. The track is specified using separate TrackDescriptor messages and
// referred to via the track's UUID.
//
// A simple TrackEvent packet specifies a timestamp, category, name and type:
// ```protobuf
// trace_packet {
// timestamp: 1000
// track_event {
// categories: ["my_cat"]
// name: "my_event"
// type: TYPE_INSTANT
// }
// }
// ```
//
// To associate an event with a custom track (e.g. a thread), the track is
// defined in a separate packet and referred to from the TrackEvent by its UUID:
// ```protobuf
// trace_packet {
// track_descriptor {
// track_uuid: 1234
// name: "my_track"
//
// // Optionally, associate the track with a thread.
// thread_descriptor {
// pid: 10
// tid: 10
// ..
// }
// }
// }
// ```
//
// A pair of TYPE_SLICE_BEGIN and _END events form a slice on the track:
//
// ```protobuf
// trace_packet {
// timestamp: 1200
// track_event {
// track_uuid: 1234
// categories: ["my_cat"]
// name: "my_slice"
// type: TYPE_SLICE_BEGIN
// }
// }
// trace_packet {
// timestamp: 1400
// track_event {
// track_uuid: 1234
// type: TYPE_SLICE_END
// }
// }
// ```
// TrackEvents also support optimizations to reduce data repetition and encoded
// data size, e.g. through data interning (names, categories, ...) and delta
// encoding of timestamps/counters. For details, see the InternedData message.
// Further, default values for attributes of events on the same sequence (e.g.
// their default track association) can be emitted as part of a
// TrackEventDefaults message.
//
// Next reserved id: 13 (up to 15). Next id: 50.

// event of A and will be drawn as a nested event underneath A in the UI.
// Note that child events should always end before their parents (e.g. B
// before A).
//
// Each slice event is formed by a pair of BEGIN + END events. The END event
// does not need to repeat any TrackEvent fields it has in common with its
// corresponding BEGIN event. Arguments and debug annotations of the BEGIN +
// END pair will be merged during trace import.
//
// Note that we deliberately chose not to support COMPLETE events (which

// a different thread - a flow between the two events can associate them.

// timestamps. The earliest event with the same flow ID becomes the source
// of the flow. Any events thereafter are intermediate steps of the flow,
