Ensure flip-function is completed before running synchronous checkpoint
Currently, there is a possibility that the target (for synchronous
checkpoint) thread is not flipped but the caller is. This could result
in accessing from-space objects or having a mix of 'from' and 'to' space
references on the target's stack. This is particularly an issue with
userfaultfd GC.
tm-mainline-prod NOTE: The change is flagged with gUseUserfaultfd to be
consistent with all the other changes in ThreadList::FlipThreadRoots.
