c2011ac9c6 Modify evttype_index_ruleset to derive from indexable_ruleset 
Modify evttype_index_ruleset to derive from indexable_ruleset instead
of having its own implementation of segregating filters by ruleset
id/event type.

An evttype_index_ruleset::wrapper contains a falco rule and filter,
and run_wrappers() evaluate the filter as before, without the
segregation by ruleset id/event type.

Done separately just in case we ever have github checks that track

605e69cf0e Add an indexable ruleset that can split filters by ruleset/evttype 
Now that custom rules loading implementations (and related, custom
rulesets) can be swapped into falco in a customizable way, there is
some functionality in evttype_index_ruleset that could be used by
other rulesets, specifically the part that segregates filters by
ruleset and enables/disables filters based on name substring + tags.

To allow for this, create a new base class indexable_ruleset that
takes a generic filter_wrapper object that can return a name, tags,
and sc/event codes, and segregates the filters by ruleset. It also
optionally segregates filters by event type.

The main interfaces are:

- an implementation of filter_wrapper to provide a name/tags/event
  codes.
- add_wrapper(), which provides a filter_wrapper to the
  indexable_ruleset.
- run_wrappers(), which must be implemented by the derived class and
  is called for event processing.

Most of the methods required by filter_ruleset are implemented by
indexable_ruleset and do not need to be implemented by the derived
class.
