LibWeb: Convert the Location object to IDL

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
