Improve ANR debug store logging with more app lifecycle events

New debug store events:
* BindApp = bind application
* SchRcv = schedule receiver
* SchRcvReg = schedule registered receiver
* BcRcvReg = broadcast receive (registered receiver)

Also changed the semantics of some existing debug store events:
* GoAsync / Finish now include the pending result id (so readers can see which finish is for which goAsync)
* Finish no longer includes the receiver name (redundant)
* HandleReceiver is renamed to BcRcv for consistency with BcRcvReg

Also:
* Added some debug logging for the debug store

The rationale for adding these events is to make broadcast_of_intent and
bind_application ANRs more debuggable.
