Linus Groh e07a39c816 LibJS: Replace 'size_t line, size_t column' with 'Optional<Position>'
This is a bit nicer for two reasons:

- The absence of line number/column information isn't based on 'values
  are zero' anymore but on Optional's value
- When reporting syntax errors with position information other than the
  current token's position we had to store line and column ourselves,
  like this:

      auto foo_start_line = m_parser_state.m_current_token.line_number();
      auto foo_start_column = m_parser_state.m_current_token.line_column();
      ...
      syntax_error("...", foo_start_line, foo_start_column);

  Which now becomes:

      auto foo_start= position();
      ...
      syntax_error("...", foo_start);

  This makes it easier to report correct positions for syntax errors
  that only emerge a few tokens later :^)
