Provide an opt-out for hiding a SDC component from XB

A proposal was done in #3485820-22: Fatal error on installing the Navigation module: `PropShape::resolveSchemaReferences(): Argument #1 ($schema) must be of type array, string given` → , to add an optional property in SDCs to opt-out from XB, e.g., hideFromUi: true in core.

I've mixed feelings about doing this in core though.

It would probably be easier to implement this way, but hideFromUI could be confusing.
Something specific like hideFromXB adds a reference to experience_builder in core. What if e.g. tomorrow the storybook module wants to add a similar one?

On the other side, SDC by definition should have everything in the same directory, so there are no hook_alters.
As we already decorate ComponentPluginManager it would still be possible though to have that in XB, but breaks the _single-directory_ contract.
