Reworking jerry_debugger_send_string method

From now on, jerry_debugger_send_string can send a subtype of the string, making it more simple to send over strings with special parameters, therefore seperating different types of messages are simpler.
Enumerations for various subtypes can be made, while there's only need to have 2 entries for the header type.
