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.

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.

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no longer valid instances of their respective classes.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 20.1.3 Properties of the Number Prototype Object
- ES11 21.1.3 Properties of the String Prototype Object

The "async" identifier processing is delayed until it is detected that it cannot

point, but it was not happened in this case.
