Change BridgeResources to Resources_Delegate [DO NOT MERGE]

Do not merge because the resource implementation has changed in N and
the change is no longer valid there.

This is a very hacky fix to make layoutlib work with the latest support
lib. Inject a couple of fields in android.content.res.Resources to
allow using most of the earlier code as is.
