Improve organization between modules.

* Rename _typing to beancount_types to better reflect what it is.
* LessComparable isn't a Beancount type, so move that to
plugin.core with its dependent helper classes.
* Errors are a core Beancount concept, so move that module to the
top level and have it include appropriate type definitions.
