[MaterialDividerItemDecoration] Request: support GridLayoutManager too

Is your feature request related to a problem? Please describe.
Currently it supports only one orientation, but not both. This is what's in code:

MaterialDividerItemDecoration divider =
    new MaterialDividerItemDecoration(getContext(), orientation);
recyclerView.addItemDecoration(divider);

Not only that, but I think it draws outside the boundary. If you can, you can compare what you make with this solution:
https://github.com/Fondesa/RecyclerViewDivider

Describe the solution you'd like
Be able to set the divider to be shown on all orientations of the layoutManager, so that it will work for a grid, too.
Maybe even make it as such by default, because on the other solution I've mentioned it doesn't require it at all.

Describe alternatives you've considered
As I wrote, this works better:
https://github.com/Fondesa/RecyclerViewDivider

The usage there is as such:

recyclerView.addDivider()

Additional context
Relevant part in the sample:
https://github.com/material-components/material-components-android/tree/master/catalog/java/io/material/catalog/divider

Inizia con l’utilizzo di MaterialDividerItemDecoration nell’esempio del catalogo e confronta il suo comportamento attuale con la soluzione RecyclerViewDivider collegata. Verifica che la modifica supporti entrambe le orientazioni con GridLayoutManager e mantenga i divisori entro i limiti del layout.
