fix: ensure ignorePrivate setting works with iterateAllJsdocs rules

This impacts rules: `checkAccess`, `checkAlignment`, `checkExamples`,
`checkIndentation`, `checkSyntax`, `checkTagNames`, `checkTypes`,
`checkValues`, `emptyTags`, `newlineAfterDescription`, `noUndefinedTypes,
`requireDescriptionCompleteSentence`, `requireHyphenBeforeParamDescription`,
`validTypes

Factors out common `iterate` code. Also ensures any future rules with
`noTrim` but without `iterateAllJsdocs` will work
