[Files app] Remove redux dependency on foreground

In CL:4806862 we want to start migrating actions_producers/*
to ducks/* but this created a dependency chain from the redux module to
the UI module (foreground/js/) which is not desirable since the UI
should depend on the state, but not the other way around.

Additionally, this caused the SWA build to break because it started
depending on the Image Loader extension (chrome-extension://pmfjbimdmchhbnneeidfognadeopoehp).

This CL fixes both issues by moving non-UI-specific shared code
from foreground/js/ into common/js/ so it can be imported by ducks
without depending on the UI module.
