Flavor for the creation of MPI windows for `PETSCSFWINDOW`

## Synopsis

    typedef enum {
      PETSCSF_WINDOW_FLAVOR_CREATE,
      PETSCSF_WINDOW_FLAVOR_DYNAMIC,
      PETSCSF_WINDOW_FLAVOR_ALLOCATE,
      PETSCSF_WINDOW_FLAVOR_SHARED
    } PetscSFWindowFlavorType;

## Values

- `PETSCSF_WINDOW_FLAVOR_CREATE` - Use `MPI_Win_create()`, no reuse

- `PETSCSF_WINDOW_FLAVOR_DYNAMIC` - Use `MPI_Win_create_dynamic()` and dynamically attach pointers

- `PETSCSF_WINDOW_FLAVOR_ALLOCATE` - Use `MPI_Win_allocate()`

- `PETSCSF_WINDOW_FLAVOR_SHARED` - Use `MPI_Win_allocate_shared()`
