fix(priority-overflow): overflowMenuSize included in occupiedSize

[ValentinaKozlova]

OverflowMenu is not included in occupiedSize.
Overflow component contains only visible overflow items or hidden ones, but hidden because they don't fit the container.
If menu has default hidden items then overflowMenu is not included into calculation.

I added a new optional prop hasHiddenItems.

make sure to run build for react-overflow, so it will update public api md file :)

[mainframev]

I think you can omit this change file as correct one is with minor bump and feature scope

[ValentinaKozlova]

Thanks for catching that. I had to run generate-api because build command ignored those changes, I've run it before
