parse.y: Fix locations of HEREDOC

* parse.y (rb_parser_set_location_from_strterm_heredoc):
  Set locations based on rb_strterm_heredoc_t.

* parse.y (yylex): Set yylloc based on rb_strterm_heredoc_t
  when parsing heredoc.

  e.g. The locations of the NODE_DSTR is changed:

  ```
  a <<STR
  123
  #{:a}
  STR
  ```

  * Before

  ```
  NODE_DSTR (line: 3, code_range: (3,0)-(1,7))
  ```

  * After

  ```
  NODE_DSTR (line: 3, code_range: (1,3)-(1,7))
  ```
