Add Proxy support for prototype handling

Cleanup get/setPrototypeOf and fix some smaller incompatibilities
in the default implementation for Object.

Add the methods to the vtable and reimplement them according to
spec for ProxyObjects.

Clean up the Object.prototype.get/setPrototypeOf/__proto__ methods
and fix a smaller bug in the Reflect API for those methods.
