Rework cmake build to a better super-project structure. (#17)

* Removes some obsolete CI packaging steps that need to be reworked in a
followon.
* Reworks patches directory to be based on `git format-patch` and `git
am` for a more sustainable dev flow.
* Takes a fine tooth comb to version propagation in the sub-projects and
burns out a lot of implicit dependencies on the host environment.
* Layers the sub-project builds for isolation and separation of concerns
so that there is less chance of implicitly depending on a byproduct out
of order.
* Implements automatic toolchain management so that sub-projects can be
configured to build with an in-project built LLVM and/or HIP compiler.
* Includes upstream patches for working around various CMake issues.
* Removes most stringly propagated CMake variables in favor for explicit
declaration in sub-projects.
* Adds the beginning of a build manual.
* Adds background build job pools that sub-projects can opt into if they
have low concurrency/high latency.
