Extract footer preference as a widget lib
Currently, developer needs to import SettingsLib to use
footer preference. But the size of SettingsLib is too huge.
We extract the footer preference as a lib so that developer
only needs to import a small lib for using footer.
Test: Rebuilt apk, and see the footer preference
Fix: 173088235
