[TIMOB-16320] Android: Integrate v7 compat library

This resolves [TIMOB-16320](https://jira.appcelerator.org/browse/TIMOB-16320) and unblocks us from continuing work on [TIMOB-15021](https://jira.appcelerator.org/browse/TIMOB-15021)

This essentially loads v7-appcompat library as a module in the titanium SDK. Also removes a bunch of unrequired resources and puts the hooks in to build namespace specific resources.

This PR has an ugly hack to get the appcompat library to be included (see update to KrollAPIUpdater.java) which should be revisited by us when we work on [TIMOB-11360](https://jira.appcelerator.org/browse/TIMOB-11360). 

For testing just build the SDK and run any titanium app. There should be no change in functionality. This PR does not change the build scripts to generate new themes based on the AppCompat library. That will be done as part of [TIMOB-15021](https://jira.appcelerator.org/browse/TIMOB-15021).
