EntityProperties archetype prototype

[Wumpf]

• Part of Introduce archetype(s?) for Visible and Interactive properties #9251

As layed out in above ticket, we need to put Interactive and Visible into an entity.

This proposal (once fully propagated) solves everything noted in #9251 and additionally:

• removes the last hold-out of "recursive overrides", allowing faster & better structured blueprint query handling in the near future
• exposes the illustrious recursive visibility to users

Drawbacks:

• Small departure from Make visualizers & archetypes map 1:1 (+notes on visualizer selection in world without indicators) #8368
  • this archetype will always be "special"
• Walking right into more things that need tagging, adding a little bit technical debt
  • flip side: this adds much wanted tagging to the components at hand

EntityProperties is a pretty poor name since it's overly general and can be confused with everything else that's on an entity. Looking for something better.

For discoverability, the central fbs definition file:

namespace rerun.archetypes;

/// General visualization properties of an entity.
///
/// TODO(#6541): Fields of this archetype currently only have an effect when logged in the blueprint store.
// TODO(#9251): Add example
table EntityProperties (
  "attr.docs.unreleased",
  "attr.docs.category": "General"
) {
    /// Whether the entity can be interacted with.
    ///
    /// Non interactive components may still be still visible, but mouse interactions in the view are disabled.
    ///
    /// Defaults to true.
    interactive: rerun.components.Interactive ("attr.rerun.component_optional", nullable, order: 100);

    /// Whether the entity is visible.
    ///
    /// If this is set, it will take precedence over the `visible_recursive` field
    /// and any `visible_recursive` setting further up in the hierarchy.
    ///
    /// Defaults to true.
    visible: rerun.components.Visible ("attr.rerun.component_optional", nullable, order: 200);

    /// Whether the entity and its children are visible.
    ///
    /// This property is propagated down the entity hierarchy until another child entity
    /// sets `visible_recursive` to a different value at which point propagation continues with that value instead.
    ///
    /// `visible_recursive` is ignored on any individual entity that has the `visible` field set.
    /// (But this does not affect tree propagation of the property)
    ///
    /// Defaults to true.
    // TODO(#6889): Use `Visible` component and rely on field tag instead.
    visible_recursive: rerun.components.VisibleRecursive ("attr.rerun.component_optional", nullable, order: 300);
}
