feature: filters events

Adds calls to the piwik.trackSiteSearch API when producers or products filters are changed

Limitation: The M.autocomplete does not seem to raise the event, I dont' know why yet.

To be validated against the core beta branch once this job is done: https://git.startinblox.com/framework/sib-core/-/jobs/30600 and before I merge to master. Console.logs are just there for validation
