Remove duplication around is_trivia functions

[dhruvmanila]

Summary

This PR removes the duplication around is_trivia functions.

There are two of them in the codebase:

1. In pycodestyle, it's for newline, indent, dedent, non-logical newline and comment
2. In the parser, it's for non-logical newline and comment

The TokenKind::is_trivia method used (1) but that's not correct in that context. So, this PR introduces a new is_non_logical_token helper method for the pycodestyle crate and updates the TokenKind::is_trivia implementation with (2).

This also means we can remove Token::is_trivia method and the standalone token_source::is_trivia function and use the one on TokenKind.
