Consider using x11 crate (static linking) instead of x11-dl or provide a feature to use x11

Description

I am currently having trouble building winit (using iced crate) with musl due to x11-dl, if this crate could use x11 crate or at least provide a feature to use it. it would be much simpler for me to use winit.

I am willing to create a pull request, if this feature is acceptable to the project.
