Coding Standards: Remove redundant ignore annotations.

This removes ignore annotations which are ignoring an error which would not be thrown for that code.

Includes tidying up the format of the ignore annotation:
* Customary one space between the `//` and the start of the comment.
* There should be no spaces in the comma-separated sniff list.

Follow-up to [45607], [47185], [49200], [53152].

Props jrf.
See #59161.
