Ioannis Ilkos 8d168e2d8a Sysprop for the count of active OOME tracing sessions 
In order for ART code to call perfetto DataSource::Trace() we need to
wait for all data source instances to have completed their setup. To do
so, we need to know how many of them exist.

This introduces a new sysprop traced.oome_heap_session.count, writeable
by perfetto traced and readable by apps and system_server that can be
used to communicate this.

See go/art-oom-heap-dump for more details

Test: manual, atest HeapprofdJavaCtsTest
