n-api: add more property defaults

Add a default value for class method and js like property in enum
napi_property_attributes.

n-api currently offers only one default which is non configurable,
non writable, non enumerable - like Object.defineProperty(). While
this is formal correct the usual way to create properties in JS is
either by defining a class or use obj.prop = value.

The defaults from these variants are now backed into enum values.
