Extract a basic grid UI view component

[mlewand]

📝 Provide a description of the new feature

Currently we only have a specialized, ColorGridView type, while there are more grids to come and some common logic can be shared between the two.

Also technically such a generic component could be reused by the table feature dropdown.

Required by #1110.

We decided this will not be a priority for now. For anyone working on this later on, there's a branch i/5772 that has a basic implementation.
