columnview: Add gtk_column_view_add_row_factory()

This allows setting a factory to toggle per-row properties.

Implemented are selectable, focusable and activatable.
These are meant to supercede the per-cell selectable and activatable
properties, which make no sense individually.

The focus property makes it possible to focus rows instead of cells,
which is the default behavior.
