WebAPK: Move MainActivity#onCreate() to runtime library
This CL decreases the amount of code in webapk/shell_apk.
webapk/shell_apk and webapk/common are the only Java files bundled in the
WebAPK. In order for the Java to updated, the WebAPK server needs to
download and install a new version of the WebAPK. Decreasing the amount of
code in webapk/shell_apk decreases how often new WebAPK versions will have
to be pushed to users.
