Record: Avoid duplicates from replaying frozen events

Reintroduce a check which used to be there in the old
ProcessKeyboardEvent/ProcessPointerEvent codepath, which avoids us
recording events subject to a grab twice: once when it's first processed
in EnqueueEvent, and then again when it's thawed and being replayed.

This required a tiny amount of code motion to expose syncEvents.
