Changes to get Bevy to compile with wgpu master. With this, on a Mac: * 2d examples look fine * ~~3d examples crash with an error specific to metal about a compilation error~~ * 3d examples work fine after enabling feature `wgpu/cross` Feature `wgpu/cross` seems to be needed only on some platforms, not sure how to know which. It was introduced in https://github.com/gfx-rs/wgpu-rs/pull/826
