Similar to get_dynamic_field_object_from_store, but returns the value in the field instead of
the Field object itself.
Get a dynamic field from the store with a generic key type. The key type may
only have phantom type parameters, because it must have a fixed serialization
format.
Given a parent object ID (e.g. a table), and a key, retrieve the corresponding dynamic field object
from the object_store. The key type K must implement MoveTypeTagTrait which has an associated
function that returns the Move type tag.
Note that this function returns the Field object itself, not the value in the field.
