Move the vuex logic out of the filter component

What does this MR do?

This refactor does a few things:

It moves all the Vuex logic out of the <filter> component used on the security dashboards. Some of this functionality has been pulled into the component as computed properties. The rest of it, has been moved up to the <filters> component.

As a result of this, there's some redundant getters that have been removed.

The <filters> spec has been migrated to Jest with some extra testing.

It even introduces the fancy new <gl-sprintf> component into the mix.

If all goes well, no one will ever notice these wonderful changes. Everything should continue as normal.
