[native][android] Move database and MMKV initialization to CommCoreJSIModulePackage
Summary: This diff prevents the Android app from getting into a state that causes a crash loop, described in ENG-7696. It however does not resolve the crash loop if it already occurring.
Test Plan:
- Deleted the app off the simulator and redeployed, and the problem was gone (app stopped crash looping after being closed/reopened)
- Deployed this fix to production and confirmed it fixed the issue for all 3 users that were affected
