Modify the usage of ecma_string_to_utf8_string()

Browse Source 
Parts:
 * Rename ecma_string_to_utf8_string() to ecma_string_copy_to_utf8_buffer.

 * Introduce ecma_string_to_utf8_bytes(), which wraps the usual 'function call-assertion' pair,
   and check strict equality of size of the string and the buffer.
