There is nothing built into Final Cut that will do that, but there may be some third party plug ins to get that look.
What I have done is take a piece of paper and tear it in half the scan the 2 halves and use them has mattes.
Put them under the video layer that you want to remove, but above the video layer you want to reveal them under Composite setting choose Travel Matte-Luminace. One you have the torn pages you can use a page turn transition to take them off or whatever you wish.
