Improved ObjectTemplate::set_*_handlers (#1237)

Browse Source 
Prior to this commit, `v8::NamedPropertyHandlerConfiguration`
and `v8::IndexedPropertyHandlerConfiguration` did not expose the
`definer` hook, or `flags`.

This commit adds these options. In the process of doing this a couple of
other changes were made:

- Bitflag enum consts are now member consts of the related struct.
  This is done because PropertyHandlerFlags has conflicts with
  PropertyAttribute.
- PropertyDescriptor gets all C++ introspection methods exposed to Rust.
- NamedPropertyHandlerConfiguration callback types get rustdoc comments.
- IndexedPropertyHandlerConfiguration callback types get rustdoc
  comments.
- GenericNamedPropertySetterCallback gets a ReturnValue parameter, to
  signal trap passthrough.
