GET_METHOD_NAMES: "__getMethodNames__" = '__getMethodNames__'

The name of the automatically added default meta-method for obtaining a list of all methods of an object declared with Far, or an object that inherits from an object declared with Far.

Modeled on GET_INTERFACE_GUARD from @endo/exo.

TODO Name to be bikeshed. Perhaps even whether it is a string or symbol to be bikeshed. See https://github.com/endojs/endo/pull/1809#discussion_r1388052454

HAZARD: Beware that an exo's interface can change across an upgrade, so remotes that cache it can become stale.
