Did we decide to also accept number arrays?

@roji I don't think this will appear on a hot path, but can you think of a faster way of implementing this?

Part of #30604 |
Part of #30730 - Type mappings now have a `JsonValueReaderWriter` that handles reading and writing JSON for the type. - This can be overridden by a `JsonValueReaderWriter` on a property, for example, to allow GeoJson to be written instead of WKT. - These are typically singleton instances, and can be optimized out for well-known cases. - If the type mapping has a converter, then the converter must be applied to the value before being written to JSON, and the converter must be applied after reading the JSON value. - If the property itself has a `JsonValueReaderWriter`, then the unconverted property value is passed to this reader/writer.
