Add them in `<Kernel/API/Device.h>` and use these to provides
`{makedev,major,minor}` in `<sys/sysmacros.h>`. It aims to be more in
line with other Unix implementations and avoid code duplication in user
land.
Since the InodeIndex encapsulates a 64 bit value, it is correct to
ensure that the Kernel is exposing the entire value and the LibC is
aware of it.
This commit requires an entire re-compile because it's essentially a
change in the Kernel ABI, together with a corresponding change in LibC.
It's technically not specified by POSIX, but it appears most Unix-like
systems worth mentioning put those definitions there. Also, it's more
logical since the dev_t type is defined there.
