Fix CollapsingToolbarLayout consuming insets

Currently it consumes insets, which means that
the insets never reach its children. Since it
does not need to consume them, lets not.

Also fixed WindowInsetsCompat so that equals(),
toString() and hashCode() work as expected.

Also ported the same equals fix to AppBarLayout
and CoordinatorLayout.
