Browser plugin should never handle MouseWheels.

Browser plugin should never handle MouseWheels.

Now that we do direct routing of MouseWheel events to guests,
BrowserPlugin should (1) never mark a MouseWheel as handled (this may
cancel GesturePinch on Mac), and (2) it should never forward the
MouseWheel to the guest. This CL implements this policy.
