I've removed the ecma_op_object_get_property_names method, and implemented the following ones:
- ecma_op_object_own_property_keys: this is now the internal [[OwnPropertyKeys]] method
- ecma_op_object_enumerate: this is used for the for-in iterator
- ecma_object_sort_property_names: this is used for sorting the property names of an object
- ecma_object_list_lazy_property_names: this is for getting the lazy instantiated properties
- ecma_object_prop_name_is_duplicated: this is for checking if a given property is duplicated in an object
Also the for-in operation with Proxy object works with this patch, #3992 should be closed

From ES 6 the ToPropertyKey operation is used to convert elements to a valid property key.
This "new" method uses the ToPrimitive operation which can call the `@@ToPrimitive`
well-known symbol to convert the given element to a key.

We can apply this change to methods which use older standards, because
of the backward compatibility the result is the same

The Date.prototype[@@toPrimitive] only allows the "string", "default" and "number"
hint values. Any other value should throw a TypeError.

As stated in ES 16.1, "arguments" and "caller" must not be created in:
- strict functions created using the Function constructor
- generator functions created using the Generator constructor
- async functions created using the AsyncFunction constructor
- functions created using the bind

ES2015 spec made an incompatible change, many builtin prototypes became
no longer valid instances of their respective classes. But unfortunately
it broke the web, so ES2016 reverted String, Boolean and Number prototype
to the original behaviour (ES5.1). JerryScript should match the latest spec.

- ES11 19.3.3 Properties of the Boolean Prototype Object
- ES11 20.1.3 Properties of the Number Prototype Object
- ES11 21.1.3 Properties of the String Prototype Object

Also a minor update to the FromPropertyDescriptor operation since in ES6 we can use a property
descriptor whitout any keys
