Multi Component Group Wrapper (#3473)

Browse Source 
[ci no changelog needed]

This PR implements a new helper for the future Component Browser - `component_group::multi::Wrapper`. It propagates FRP events from multiple component groups and ensures that only a single component group is focused at all times.

See the updated component group demo scene (console logs shows propagated FRP events from all component groups):

- Fixed a `define_endpoints_2!` macro. FRP endpoints for `focus` events weren't connected properly.
- List View now uses an overlay shape to catch mouse events, it allows much easier implementation of `is_header_selected` in the component group.
