keyboard: remove shortcuts_model

This appears to be largely vestigial code from a time when a GtkTreeView
was used here. It is very confusing, because someone reading the code
expects this to be critical to what's displayed on the screen, but it
isn't.

If I understand correctly, the only place this was still useful for
something was in `cc_keyboard_manager_remove_custom_shortcut()`, to check
that the CcKeyboardItem is valid. If I understand, this is a sanity
check that should never fail, so this seems unnecessary, and I've
removed it.

If that check is actually important, it would be better to have a
`GHashTable` of custom shortcuts, which should be simpler and clearer.

`sections_store` should similarly be removed/replaced. It seems to only
be needed in `add_shortcuts()`. But that seems like it can't just be
removed, so I haven't changed that yet.
