Allow interrupting GetMultiXactIdMembers
This function has a loop which can lead to uninterruptible process
"stalls" (actually infinite loops) when some bugs are triggered. Avoid
that unpleasant situation by adding a check for interrupts in a place
that shouldn't degrade performance in the normal case.
Backpatch to 9.3. Older branches have an identical loop here, but the
aforementioned bugs are only a problem starting in 9.3 so there doesn't
seem to be any point in backpatching any further.
