Optimizes memory and CPU usage in JSONCodec (#13545)
The null element and the empty JSONArray are frequently created and used
as temporary objects to be encoded by the json encoder. Because they are
never manipulated it is possible to reuse the same empty element again
and save a significant amount of temp objects.
This also helps jsonEquals, which then can return faster due to:
if (fieldValue == referenceValue) return true
jsonEquals does not need to check the referenceValue for JSONobject.NULL.
The invoking code makes sure this never happens.
Boolean and Integer values are very often and much more efficiently
compared directly instead of using toString.
