Use the Perfetto SDK instead of ATRACE

Perfetto has significantly less overhead. The User facing API is
mostly unchanged:

Here are the differences:

- SYSTRACE_ENABLE() does nothing on ANDROID, initializes systraces on darwin.
- SYSTRACE_DISABLE() is removed.
- A new "gltfio" tag is added.
- SYSTRACE_TAG *must* be defined before including `utils/Systrace.h`
- `utils/Systrace.h` should not be used from a public header
- the new SYSTRACE_TAG_DISABLE disables systrace at compile time


For android a data source MUST be created in the perfetto config:

```
data_sources {
  config {
    name: "track_event"
    track_event_config {
      enabled_categories: ["filament", "jobsystem", "gltfio"]
      disabled_categories: "*"
    }
  }
}
```

This can for example be added to AGI's custom/advanced config.
