feat: enabled prop for KeyboardStickyView (#717)

## 📜 Description

Added `enabled` property for `KeyboardStickyView` component. Also added
this property to `KeyboardToolbar`.

## 💡 Motivation and Context

On top of what I remember this is iOS itself moves `KeyboardToolbar` (i.
e. it's not interactive keyboard dismissal). So to fix the problem I
decided to add `enabled` property. Using this property you can assure
that views on previous screens are not animating/don't require
additional style/layout computation.

A similar approach was used by
`KeyboardAvoidingView`/`KeyboardAwareScrollView` components.

> Even though if we fixed the problem of keeping `KeyboardToolbar`
toughly bind to keyboard frame - on interactive gesture we would still
see a `KeyboardToolbar` without a keyboard. So `enabled` property is the
way to go at the moment.

Closes
#716
