Introduce preserveLegacyExternalStorage manifest attribute 

This attribute will default to false and does nothing in the false
state.

In the true state, it will allow an updating app preserve any legacy
storage access from the existing installed version on device.

             For an updating app, setting this to {@code true} will preserve the legacy behaviour

             configured by the {@code requestLegacyExternalStorage} flag. If on an update, this

             flag is set to {@code false} then the legacy access is not preserved, such an app can

             only have legacy access with the {@code requestLegacyExternalStorage} flag.

             <p>



             The default value is {@code false}.
