andrewlewis eddc2b0b33 Enable multidex for demos
This is necessary now we have Guava in debug (no-minified) apps.

Also switch to AndroidX multidex to remove the support library dependency.
Temporarily we need to add an Application class, as internal jetification
doesn't seem to handle declaring MultiDexApplication in AndroidManifest.xml.
