 Lazy-load visibility properties in `BP_XProfile_Field`.

 Previously, populating a new `BP_XProfile_Field` object would result in
 two
 queries: one to fetch the field row from the database, and one to populate
 the
 field meta cache in order to set the 'allow_custom_visibility' and
 'default_visibility' properties. It's not often the case that we need the
 latter properties, which means that the cache-priming query is wasted.

 This changeset addresses the shortcoming by loading the properties only
 when
 they're requested:

 * `$allow_custom_visibility` and `$default_visibility` are now protected
 properties of the object. This directs requests for them to the magic
 methods.
 * Introduce `__isset()` and `__get()` to handle backward compatibility.
 * Introduce public getter functions for each property.

 See #6638.
