Improve typedArray get, set (#3023)

Browse Source 
Here are the following changes:
  - The getter and setter methods are callback based now, and we can use
    them with the proper typedArray id
  - The typedArray set_element and get_element methods are using memcpy now.
  - There is a new struct which contains basic informations from typedArray,
    and we are using this in most of the prototype methods.
  - Eliminated ecma_op_typedarray_set_index_prop and
    ecma_op_typedarray_get_index_prop, because these methods
    also calculated the same informations which are in the new
    struct, so we use the new method instead.
