Péter Gál 5d51fe8f27 Fix TypedArray.slice with external array buffer (#3080)
In case of TypedArrays which were constructed with an ArrayBuffer
the `slice` method incorrectly added the `byteOffset` value of
when the elements were copied.

There is no need to add the `byteOffset` value for the ArrayBuffer's
contents pointer as it is already added by the `ecma_typedarray_get_buffer`
call.
