VolumeManager from background page

Refactor FilteredVolumeManager() to not depend or reach to the
background window/page, instead it just receives a promise that resolves
to the `VolumeManager` which is what `FilteredVolumeManager()` needs.

This is a preparation for JS modules to avoid the foreground using
global variables from the background, this case is avoiding the
`volumeManagerFactory` from FilteredVolumeManager().

For the SWA is the same concept, centralize the interaction with
background page via the `BackgroundPage` interface.

No change in the behavior, so Closure and current tests cover this.
