LibWeb: Delete LegacyPlatformObject and move behavior to PlatformObject We have two known PlatformObjects that need to implement some of the behavior of LegacyPlatformObjects to date: Window, and HTMLFormElement. To make this not require double (or virtual) inheritance of PlatformObject, move the behavior of LegacyPlatformObject into PlatformObject. The selection of LegacyPlatformObject behavior is done with a new bitfield of feature flags instead of a dozen virtual functions that return bool. This change simplifies every class involved in the diff with the notable exception of Window, which now needs some ugly const casts to implement named property access.

// ^Bindings::PlatformObject
LibWeb: Let supported_property_names() return Vector<FlyString> Ultimately, this API should probably be replaced with something that updates a cache on relevant DOM mutations instead of regenerating the list of property names again and again.

virtual Vector<FlyString> supported_property_names() const override;
Bindings: Make item_value return an Optional<JS::Value> This removes some ambiguity about what the return value should be if the index is out of range. Previously, we would sometimes return a JS null, and other times a JS undefined. It will also let us fold together the checks for whether an index is a supported property index, followed by getting the value just afterwards.
