Remove RenderWidgetHostImpl::SuppressEventsUntilKeyDown()

This revert https://codereview.chromium.org/12221133 where the
suppression on focus was originally added. No tests were added, but the
manual test described now passes without this code. There is of course
some chance that it is needed for some other case, so this CL should be
revert at the first sign of trouble.

The reason for this change is that the suppression on focus causes the
PrintScreen KeyUp event to be dropped.
