Summary:
The [post](https://fb.workplace.com/groups/oculusplatformsdk/permalink/1303649500796461/) explains why we are doing the change.
There will be many diffs, each changing 50 files, until we are done.

The transformation rules below come from the [PackageHelpers.java](https://www.internalfb.com/code/fbsource/[beda88384dad]/arvr/apps/SystemShell/Common/PackageUtils/java/com/oculus/common/packageutils/PackageHelpers.java?lines=671-682) file:
* Removing from application.meta-data means adding category in every application.activity, in every child intent-filter
* Removing from activity.meta-data means adding category in current activity, in every child intent-filter
