NewAKString is effectively the default for any new IDL interface, so
let's mark this as the default behavior. It also makes it much easier to
figure out whatever interfaces are still left to port over to new AK
String.
This includes:
- Moving it from Bindings/ to HTML/
- Renaming it from LocationObject to Location
- Removing the manual definitions of the constructor and prototype
- Removing special handling of the Location interface from the bindings
generator
- Converting the JS_DEFINE_NATIVE_FUNCTIONs to regular functions
returning DeprecatedString instead of PrimitiveString
- Adding missing (no-op) setters for the various attributes, which are
expected to exist by the bindings generator
