RNMobile: Fix autoscroll on ListBlock (#15048)

* RNMobile: Add ability to send extra props (i.e. props needed just for mobile) to the list block.

* Adding onCaretVerticalPositionChange to RichText via context

* Passing onCaretVerticalPositionChange via context to RichText for all RichText based blocks

This makes it not necessary to pass onCaretVerticalPositionChange as a prop directly to RichText from the block component.

* Update jest snapshot for block-edit
