There is only a single callsite right now which extracts changes from a
ChangesAccess and converts them into SingleChangeAccesses, which is
inside the ChangesAccess class itself. We're about to convert push rules
such that they can both drive single and bulk push rules, and there
we'll need the same functionality.

Extract the code into a standalone `#single_change_accesses()` function
which can be used to do the conversion.

Push rules are only available in the Enterprise Edition and are thus
mixed into the BaseSingleChecker via a separate EE module which extends
the base class. This only makes push rules available for this single
checks: bulk checks ain't got any access to them, and until now they
haven't needed any either. We're about to refactor push rules to allow
batching of access checks though, so we need access to push rules in
both classes.

Move the push rule implementation into the BaseChecker class. This is
the parent class of both BaseSingleChecker and BaseBulkChecker, so it
will make the function available to both.
