Doc: add comments about PreventInTransactionBlock/IsInTransactionBlock.

Add a little to the header comments for these functions to make it
clearer what guarantees about commit behavior are provided to callers.
(See commit f92944137 for context.)

Although this is only a comment change, it's really documentation
aimed at authors of extensions, so it seems appropriate to back-patch.

Yugo Nagata and Tom Lane, per further discussion of bug #17434.
