[Feature Request] Add mouse wheel gesture support for navigation in v-carousel / v-window

Problem to solve

Currently, users can navigate the v-carousel using touch swipe gestures, navigation arrows, or pagination dots. However, desktop users frequently rely on their mouse wheel or trackpad scroll to navigate through horizontal galleries or sliding content.

When a desktop user hovers over a large carousel and instinctively scrolls their mouse wheel, nothing happens (or the whole page scrolls, depending on the layout). This breaks the expected user experience, especially in full-screen image galleries, presentations, or horizontal content sliders where mouse-wheel navigation is an industry standard. While touch devices are well-supported, desktop interaction feels incomplete without wheel support.

Proposed solution

I propose adding a native wheel event listener to the v-carousel (or the underlying v-window component) to allow users to scroll through items.

Start by tracing the v-carousel and v-window components and their existing touch-swipe navigation. Determine the intended wheel and trackpad behavior, including how navigation should interact with normal page scrolling, then verify the result with the relevant component tests or add coverage if none is identified.
