Bindgen doesn't expand C macros, which makes DRM_IOCTL_VGEM_FENCE_ATTACH
and DRM_IOCTL_VGEM_FENCE_SIGNAL not accessible through the Rust
bindings. So, move the IOCTLs numbers to a enum, preserving the same
values and the same name. This won't produce any functional changes to
the UAPI and it will make it possible to use this UAPI in Rust.
