Fix DbArray support Non-native JSON-backed arrays for Integer (so MySQL, Oracle, SQLServer etc) (#3893)

Browse Source 
Without this fix, a DbArray of List<Integer> on the plaforms that do NOT natively
support it like MySQL, Oracle, SQL Server fallback to a JSON array and this didn't
support all the specific types like Integer.

This adds the appropriate element converters when reading values, including Integer, Long, floating-point, BigDecimal, date/time, and UUID types. This prevents JSON numeric values from being returned as Long for List<Integer> properties.
