[builtins] Migrate a bunch of Object builtins to C++.

The Object.freeze, Object.isExtensible, Object.isFrozen,
Object.isSealed, Object.preventExtensions and Object.seal builtins were
already implemented in C++, but they still had some funny JavaScript
wrappers that just called into the C++ implementation on every
(interesting) execution path.

Hey Toon,

Reduce useless overhead for C++ builtins on Object.
Please take a look.

Thanks,
Benedikt
