Move all ProvisionFetcher classes out of android/ subdirectories.
The Cast Linux build will use this interface to provision devices
from the "media" service. Move these classes into general subdirs and
update BUILD.gn files so that these build on Linux.
The only non-mechanical change in this CL is that
content::CreateProvisionFetcher() now takes a net::URLRequestContextGetter*
instead of a RenderFrameHost*. This will allow more flexibility for content
embedders like Chromecast to use this class.
