contact.settings, filter.settings, search.settings etc. all have dependencies, which violates the basic rule of simple config

Problem/Motivation

Simple config has one basic rule: that it cannot depend on other config entities.

Unfortunately, lots of violations were discovered while adding validation constraints to simple config for #2952037: [meta] Add constraints to all simple configuration:

• book.settings (see #3422862-3: Add validation constraints to book.settings)
• filter.settings (see #3395562: Add validation constraints to filter.settings) → this has a specific issue already, which will make it disappear: #1932544: Remove all traces of fallback format concept from the (admin) UI
• contact.settings (see #3422872-4: Add validation constraints to contact.settings)
• search.settings (see #3425875-4: Add validation constraints to search.settings
• core.menu.static_menu_link_overrides (see #3441434-6: Add validation constraints to core.menu.schema.yml
