Use a long lived WaitEventSet for WaitLatch().
Create LatchWaitSet at backend startup time, and use it to implement
WaitLatch(). This avoids repeated epoll/kqueue setup and teardown
system calls.
Reorder SubPostmasterMain() slightly so that we restore the postmaster
pipe and Windows signal emulation before we reach InitPostmasterChild(),
to make this work in EXEC_BACKEND builds.
