feat(sharing): Allow to set default view mode for public shares

[susnux]

• Resolves Allow to default to grid view when sharing link #17762

Summary

Allow to set the default view mode for public shares.
User shares allow the user to define it themself and saves it on their user config, but for public shares this is not available.
So let the sharer allow to define the default view mode.

LGTM code and function.

However it feels off to have view controls in the share settings (I am aware this was there before) but maybe the toggle/checkbox can be moved out and displayed on the actual file list controls.

Similar concern as Fon regarding the cost/benefice of this feature. Where the cost is having yet another config option.

I agree with the concern raised @susnux
Anything against just defaulting with grid-view for share links?

Yes it only makes sense for images / videos. I would say thats not the majority of Nextcloud use cases.
If you share files it makes no sense to see it in list view.

Where the cost is having yet another config option.

Well its just a checkbox, nothing new in the backend.

I think we have both use cases of sharing images and sharing documents / files.
From my experience (but that might be biased) in most cases it is about sharing documents where list view makes sense, but of course some people might want to share images where the grid view makes sense.

Haven an option here allows users to decide which one is the best based on their use case instead of some use case we assume.
