If the prototype of a fast array is changed, for example to a Proxy object,
the array should be converted back to a normal array. This is required to
correctly handle any [[Get]]/[[Set]]/etc... calls which should trigger
these method calls on the before mentioned Proxy object.

The ECMA_OBJECT_IS_PROXY(proto_p) check is necessary throughout the prototype chain
not just at the beginning

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

Now the following conventions are applied:
- passing the number of arguments for a function call is always uint32_t
- string size/length/position related operation should use lit_utf8_size_t
- Extended objects internal fields must be uint32_t

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

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no longer valid instances of their respective classes.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 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

A list of changes:
- 'es2015-subset' profile is deprecated, and an 'es.next' profile is added.
- The default profile is changed to 'es.next'
- Renamed the JERRY_ES2015 guard to JERRY_ESNEXT
- Renamed JERRY_ES2015_BUILTIN_* guards to JERRY_BUILTIN_*
- Moved es2015 specific tests to a new 'es.next' subdirectory
- Updated docs, targets, and test runners to reflect these changes
Resolves#3737.

When the getOwnPropertyDescriptor method was invoked the input property
descriptor was not cleared in every case. This could lead to problems when
the property descriptor is not set/modified by the getOwnPropertyDescriptor
call, resulting in a failure at a later state.
Related to this the Proxy getOwnPropertyDescriptor method incorrectly returned
"undefined" value in a single case.
