Introduce CrashRecovery Adaptor

This will enable us to move CrashRecovery files out of platform into
separate apex behind flag.
Platform would be using:
1. Pre-modularization adaptor: When CrashRecovery is part of platoform
2. Post-modularization adaptor: When CrashRecovery apex is created.

We will control this behaviour using RELEASE_CRASHRECOVERY build flag.

Bug: 289203818
Test: device boots and crashrecovery service is started
Flag: build.release_crashrecovery_module
