Like Object.assign but at the reflective level of property descriptors
rather than property values.
Unlike Object.assign, this includes all own properties, whether enumerable
or not. An original accessor property is copied by sharing its getter and
setter, rather than calling the getter to obtain a value. If an original
property is non-configurable, a property of the same name on a later original
that would conflict instead causes the call to objectMetaAssign to throw an
error.
