Willie Koomson cfb1ee9eec Write tokenized user interaction extras to usage stats files

Adds support in IntervalStats obfuscation for writing arbitrary user
interaction extras. The bundle keys are tokenized, and then the bundle
is flattened to string and stored in the proto.

Bug: 440630000
Test: manual, checking widget event extras after a reboot
Test: FrameworksServicesTests:IntervalStatsTest
Flag: android.appwidget.flags.engagement_metrics

Conventions for the protos in this directory:

As in the rest of Android, use 4 spaces to indent instead of 2.
For protos based on Java files, use the same package as the Java file. For example, com.android.server.thing instead of com.android.server.thing.proto.
If the proto describes the top level output of dumpsys, it should contain Dump. This makes it easy to understand that the proto is the dumpsys output of a certain service, not the data structure of that service, e.g. WindowManagerServiceDumpProto vs WindowManagerServiceProto.
- Inner messages whose containing messages have the Proto suffix do not need to have a Proto suffix. E.g:

message FooProto {
    message Bar {
        ...
    }
}

vs

message FooProto {
    message BarProto {
        ...
    }
}

If the proto represents the structure of an object, it should have Proto as its suffix. Please also include the full package path of the original object as a comment to the proto message.
Include units in the field names. For example, screen_time_ms vs screen_time, or file_size_bytes or file_size_mebibytes vs file_size.
Leave field numbers 50,000 - 100,000 reserved for OEMs.
