Rewrite blockRollbackManager (1/n)
This is an effort to fix flaky testEnableRollbackTimeoutFailsRollback.
RollbackManager#blockRollbackManager doesn't work as intended because
PackageManagerService can't dispatch ENABLE_ROLLBACK_TIMEOUT until
abortBroadcast is called by RollbackManagerServiceImpl which happens
after blocking is finished.
See https://b.corp.google.com/issues/144732395#comment4 for a detailed
explanation.
blockRollbackManager is rewritten such that:
1. blocking takes effect only after ACTION_PACKAGE_ENABLE_ROLLBACK is
received.
2. allows tests which involves multi-package install where multiple
ACTION_PACKAGE_ENABLE_ROLLBACK will be broadcasted.
3. ENABLE_ROLLBACK_TIMEOUT now will be dispatched without waiting for
blocking to finish.
