[PATCH] D75621: [clang-tidy] Use ; as separator for HeaderFileExtensions

[Nathan James via Phabricator via cfe-commits]

njames93 added a comment.

The `llvm::StringRef::split` function can take multiple split characters, So it would be best to split on both for the time being but mark cases where `,` is used as deprecated. This way we keep the options in line with other clang-tidy checks but keep some backwards compatibility but in future change it to just using `;`
