AuditEvents: Allow to Pass File Source

Filters have no way to collect the file source from the AuditEvents as the class does not carry that information and there is no other interactions to get this information from,

TreeWalkerAuditEvents do actually collect the file source and are able to pass that on to TreeWalkerFilters.

We should expand normal AuditEvents to also send the source to be used in filters when it concerns violations to be used in filters.

Doing this may allow us to deprecate SuppressWarningsHolder as it is not really considered appropriate for how it does it's functionality. This won't allow removing SuppressWarningsHolder because the check still analyzes the AST. Maybe it should be considered if it should be a TreeWalker filter.
