Follow up on #17695 and #17696

By default, the "Week", "Day", "Month" and "Agenda" (also named "List" or "Planning") views should be enabled.
But the user should be able to disable some of those views.

In this PR:

• Create a new prop to define the enabled views
• Adapt the UI to correctly hide any non-needed view switch

Not in this PR:

• The ability to add custom views
• The ability to tree-shake the unused views (will be important in the future)
