The toJSON method should be searched on the `this` object
only once. In case of normal objects there were no problems
however when a Proxy object is used as the `this` argument
for the Date.prototype.toJSON method the Proxy's `get` method
was invoked twice.

Removed the enumerable option when listing properties to prevent an extra
[[GetOwnProperty]] function call for Proxy objects.
In this case all the property names are collected, but the Object.assign()
implementation has already taken care of the enumerable property filtering.

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.

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

In case of Proxy objects, there were no property descriptor checks when
collecting enumerable properties. Therefore, all the non-enumerable
Proxy.target properties were listed as well.

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no longer valid instances of their respective classes.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.

The "async" identifier processing is delayed until it is detected that it cannot
be part of an arrow expression. The "async" identifier should be processed at this
point, but it was not happened in this case.
