Fix the types of builtin prototype objects (#3922)

Browse Source 
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no longer valid instances of their respective classes.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.

references:
- 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
