feat(react-dialog): add support to keep dialog mounted on close

[marcosmoura]

Previous Behavior

Dialog will always unmount the DOM element on close.

New Behavior

Dialog now has a new prop (unmountOnClose) to keep the element mounted on close, allowing the Dialog to restore its state when opening again
