Preview Dictionary and Array values in the inspector instead of showing size.

This effectively removes the array or dictionary size from the 'array preview' which is a very useful UX thing.

I would suggest making / waiting for a proposal for a complete redesign of this array or dict preview, because I don't think the design this PR is an improvement from the current UX. The icons are very small and barely readable. There is more information in this preview, but I could argue that that information is not necessarily more useful.

This is a great improvement to me, but I think the size should still be displayed at the beginning (e.g. between parentheses).

For instance:

• (3) [3, 6, 9]
• (2) {"hello": "world", "foo": "bar}

This could also be (size 3) but then it'd take much more space, and horizontal space is already at a premium here.

From the one hand, this allows to see elements without unfolding which is great.
From the other hand, I can't tell where is PackedVector2Array and where is just typed array with Vector2 😆

Added size.

It's displayed differently ([V2] icon, and Arr icon + type info).

I think previewing dictionary and array contents isn't very helpful, especially since they're rarely used with so few items. Imagine trying to preview textures or scenes here. Maybe something like this would work better:

Alternatively, we could display arrays/dictionaries more efficiently by merging property names and values into a single line. The preview could be slightly grayed out and displayed only when there's enough space. We could add options in editor settings to toggle these previews on/off and adjust their threshold.

I like the changing the preview color o mark a clearer distinction between the two but mixing the property name and value is clearly a no for me. This would make it too much different from all others property editors and would dilute information and make it harder to read.
