checkpointer: Request checkpoint via latch instead of signal The motivation for this change is that a future commit will use SIGINT for another purpose (postmaster requesting WAL access to be shut down) and that there no other signals that we could readily use (see code comment for the reason why SIGTERM shouldn't be used). But it's also a tad nicer / more efficient to use SetLatch(), as it avoids sending signals when checkpointer already is busy.
