[chromium] Add gn arg to allow overriding prebuilt packages

The normal workflow for developing chromium with a fuchsia checkout
involves modifying the Fuchsia amber repo, which can accidentally revert
to the prebuilt version if Fuchsia is rebuilt. As another option, add a
gn arg to have the Fuchsia build read the far directly from a
Chromium build, ignoring the prebuilt.
