Don't create app data dirs if app requests not to
App can set a android.internal.PROPERTY_NO_APP_DATA_STORAGE property in it's
AndroidManifest.xml which will tell platform to avoid creating data
directories for it.
This property is intentionally not exposed as public API because not
having private app storage is a very niche requirement.
This change also logic to prevent app updates from changing value of the
property, i.e.: if an installed app doesn't specify value of the
PROPERTY_NO_APP_DATA_STORAGE property (or has it set to false), then any
update to this app shouldn't have this property specified (or explicitly
set it to false). If an app has PROPERTY_NO_APP_DATA_STORAGE set to
true, then all updates should keep that property set to true.
Note: this change only takes into account internal storage. Removing
app's external storage will be done in the follow up cl.
