Allow trailing comments after supression comments

[zanieb]

We should allow content to follow suppression comments e.g. to provide a reason for the # noqa.

We need to decide on a format to support with considerations of compatibility with other tools.

Previously discussed in:

• File-scoped flake8: noqa directive with comment is not recognized #10239
• Formatter: single_line_format_skip_with_multiple_comments preview style #8892
• Allow additional text following formatter pragma comments #8876

I have been using -- since it was encouraged by this ESLint rule.

I'm not personally too particular about the format. However, I think it would be wise to ensure compatibility with both Flake8 and Black since many incoming codebases are migrated from one or both.

I also think it's important that this enhancement does not break compatibility with Pyright/Mypy suppressions on the same line. This is not an uncommon occurrence, since something that violates the type system likely also violates one or more lint rules.
