Keyboard (IME) animation support (#142)

* Initial sample for IME Animations

* Initial support for WindowInsetsAnimations

* Add new imePadding() and navigationBarsWithImePadding()

* Improve visuals of the sample

* Tidy up updating of insets

* Optimize navigationBarsWithImePadding()

Currently we create a new Modifier instance on each
inset value change since we compute a new insets inside of
composed { }, which isn't ideal. Instead, we have now moved
the computation within the layout block, which means only the
layout block will be restarted on composition changes.

* Add fast-path for coerceEachDimensionAtLeast()

* Extract WindowInsetsAnimations impl to class

Also added a enable/disable flag to ProvideWindowInsets

* Extract IME Animation support to new functions

These are now behind an experimental flag

* Add animation support for remaining Insets types
