[clang-tidy] Added command line option `fix-notes`
Added an option to control whether to apply the fixes found in notes attached to clang tidy errors or not.
Diagnostics may contain multiple notes each offering different ways to fix the issue, for that reason the default behaviour should be to not look at fixes found in notes.
Instead offer up all the available fix-its in the output but don't try to apply the first one unless `-fix-notes` is supplied.
