replace libwayland with shimizu

[leroycep]

Not done yet, some of the things that need work:

• The Vulkan Swapchain extension is mysteriously working, even though I am passing a null pointer to it. Might just be my setup that it is working on though.

• Need to figure if we can proxy libwayland functions properly

• Do a treatment similar to wayland-headers (or just reuse wayland-headers?) so the build is not reliant on the freedesktop gitlab servers.

• By selecting this checkbox, I agree to license my contributions to this project under the license(s) described in the LICENSE file, and I have the right to do so or have received permission to do so by an employer or client I am producing work for whom has this right.

Edit: I figured out why the swapchain is mysteriously working:

warning: unknown object id = 0x32
error(mach): An unknown error occured while trying to connect to Wayland

Falling back to X11

I'm an idiot 🤦
