CHerry pick Include pak files in the WebView apk.

This change makes the webviewchromium.apk include the Chromium
native resource .pak files. The main reason for the complexity
of the change is the fact that the .pak files are generated by
the build system and therefore need to be copied to the target
folder before the AAPT invocation.
