Make slidesPerView: 'auto' compatible with virtual slides mode.

[ahimik]

Clear and concise description of the problem

We are currently using slidesPerView: 'auto' with predefined slide widths, which works perfectly for our UI requirements. This approach allows our layout to adapt seamlessly to varying screen sizes by automatically adjusting the number of visible slides based on their widths and the spacing between them.

However, we have more than 50 slides in our implementation, and to optimize performance, we would like to leverage the virtual slide rendering mode to dynamically load slides. Unfortunately, we’ve found that slidesPerView: 'auto' is not currently compatible with the virtual mode, as virtual rendering requires an exact number for slidesPerView. This limitation conflicts with our design, where slide widths and spacing may vary depending on the screen size.

Suggested solution

Simply allow specifying a fixed slide width using a slideWidth: number parameter. The number of visible slides could then be calculated by dividing the Swiper width by the specified slideWidth plus the gap. This enhancement would enable the combination of the slidesPerView: 'auto' option with the virtual: true rendering mode.
