Currently there are a lot of props/events/collections, as well as other code changes, in the angular grids base code that are added for correct cross-platform code generation but are not relevant to the angular component itself. Such as all members that are marked as hidden/internal but also have /* blazorInclude */ tag. There are probably other instances of fixes and overrides specifically added for elements.

We want all of those to exist only for the elements grid's and be removed from angular. Hence the grids can be extended in the elements projects as separate components and have all such members moved there.
