Create SettingsTransitionActivity

SettingsTransitionActivity is an abstract activity being in charge of
the transition feature. Activities extending it will get settings
transition applied.

We make CollapsingToolbarBaseActivity extend this activity. Clients
extending CollapsingToolbarBaseActivity will have both app bar behaviour
and the transition applied.

Also add android:transitionName into the collapsing layout, so the
transition would start from the back arrow on the action bar.

And bump the min_sdk to 29 to relevant dependencies.
