WIP - feat: Inform users when reached limit of active static filter lists [#1201]

Marked as WIP due to the following TO-DO's:

• add initialization logic
• handle cases where this module wasn't used to add/remove subscriptions and the sdk was used by mistake
• test the behavior of the bucket subscription lists when sdk adds/removes/enables/disables subscriptions

This MR includes the following changes strictly related to the ticket:

• Introduction of a buckets module to categorize subscriptions by ranks and used it to decide if a subscription gets enabled or not, and automatically disable low ranked ones to make space for new higher ranked. Required to (as-close-as) always be able to install/activate "Acceptable Ads" and "Premium" subscriptions.
  • see module overview: (internal) https://docs.google.com/presentation/d/1P0fIAYjMz-vaBN3C9gSqCSRHSmtZR4JvCOA1lyR44ks/edit?usp=sharing
• Introduction of an pseudo-disabled attribute ("toggleDisabled") that would stop a button/toggle to be 'checked' on click events and will rather show an information tooltip.
• A module ("filter-list-errors") that will handle the tooltip errors related to this ticket. In the future, it could also be the one handling all other errors related to filter Lists, like sync errors.
• Introduction of an auxiliary tooltip (io-popout) to show errors across the whole document
• Introduction of a "close" event for io-popout elements, so we can

and the following changes initially unrelated to the ticket but needed to be fixed due to ticket changes:

• Introduction of a data-state attribute in the acceptable ads (AA) form, to identify a waiting process for changing between AA subscriptions and avoid an undesired flickering effect for elements like the Survey Tooltip.
