freeglut: Add support for Wayland

[jwillikers]

Specify library name and version: freeglut/*

Adds the with_wayland option to build with support for Wayland.
Both Wayland and X11 support cannot currently be enabled simultaneously for freeglut.
It's weird.

Includes some patches to improve how the dependencies are picked up to avoid pulling in dependencies that aren't provided by Conan.

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.
