Fix #3803: Bazel/Gradle Support on Kitkat [BLOCKED on #3804]

[anandwana001]

Explanation

Fix #3803

APK supports on Kitkat when built using Gradle.

APK is building using Bazel, but crash when run on Kitkat version with the following errors:

1. Not able to bind the vector tag on the splash screen
2. Unable to start service androidx.work.impl.background.systemalarm.SystemAlarmService@9d1ab7c0

The permission issue can be solved using adding permission to manifest
, but need to figure out the exact reason why KitKat needs this permission.

@anandwana001 this isn't introducing bundle support yet since it isn't using android_application--can you try out that target first to see if it works before separating out data module?

@anandwana001 now that #3750 exists please update this to be branched off of that & update the approach to change the flavors defined in build_flavors.bzl, instead.

The current implementation in this PR works when built and install using gradle.

Getting following error with Bazel.

@anandwana001 do we have an issue tracking the latest KitKat issue (the SVG issue)?

Also, can you please update the PR title & description to more correctly describe what this PR is actually doing? We now have AAB support checked in, so the current title is no longer correct.
