Allow individual item deletion in To-do list

[DCSBL]

Proposed change

Allow deleting individual items when .DELETE_TODO_ITEM is set.

For the normal to-do list this is a nice to have, but for lists where .UPDATE_TODO_ITEM is not set you can't delete items at all. (Checkbox is hidden, so no delete-all option). This is required for the Picnic shopping cart (home-assistant/core#102855)

Can we only show this option when UPDATE_TODO_ITEM is not available? It gets very crowded in the UI with all the elements

[DCSBL]

Sure! Added that in latest commit.
I am sure people want to delete items individually even when they can edit them. So maybe adding something else to allow this while still keeping it clean. But I am not a designer 🤷‍♂️

Yes, we will have to come up with a good UX for that 👍
