35af35381a kernel: integrate kernel into main monorepo 
This moves the kernel into the main monorepo, allowing it to share
packages with the rest of the system. This change will allow us to
reduce the number of rebuilds that take place, as well as reducing disk
usage.

Note that the loader is still an indepenent project, and the integration
of that into the monorepo is pending.

afcef0d05b kernel: use vendered version of utralib 
By vendoring this package, we can avoid causing a rebuild unnecessarily.

This will be removed when Rust 1.55 is released and we can bring the
`kernel` package back into the main workspace.

9a50de8b4e refactor: utra -> utralib naming 
this cleans up some namespace issues when including
the utra crate which also refers to utra::generated::utra,
and there are CONST at the crate-level, and also functions
at the module-level which need disambiguation. By naming
the crate utra-lib this saves a bit of syntatic wrangling
at the top of every file.

bb17038bfe kernel: rename "xous" to "xous-kernel" in import 
Cargo appears to cache packages in the workspace when multiple packages
use the same crate. Unfortunately, Xous uses different features
depending on whether it's running in the kernel or in userspace.

Pull the kernel version of "xous" in under a different namespace in
order to force it to use a different build.
