DO NOT MERGE Refactor find and select dialogs

(Cherry picked from master, https://android-git.corp.google.com/g/#change,53491 )

(This is a work in progress -- assets in particular are not final)

Use common code when showing the select and find dialogs. Both
now use similarly constructed contextual action bars and share
resources where possible. Both share a common base class so
supporting code can communicate with either.

Companion changes in frameworks/base and external/webkit
