implementing concurrent codec metrics
Following changes are made in this CL:
- extend IResourceManagerService interface to allow:
- notify create/start/stop of codecs
- implement concurrent codec metrics with different
buckets (such as different resolution, codec type)
for all the application/process and for the system.
- push the codec concurrency metrics to statsd
- move all metrics to a different class
- update codec reported metrics with codec id
Bug: 265488359
Test: atest cts/tests/media/misc/src/android/media/misc/cts/ResourceManagerTest.java
/data/nativetest64/ResourceManagerService_test/ResourceManagerService_test
/data/nativetest64/ResourceObserverService_test/ResourceObserverService_test
refactoring CL. Existing unit tests still pass.
