The kernel should run in a `no_std` environment, which means it must
currently run without `alloc`. We have our own allocation methods when
running on baremetal hardware.
Begin the work to break out the allocation method so that it will work
on both desktop and baremetal environments.

The kernel and userspace both need to use `xous`, but have different
requirements. If we use a workspace, then all instances of `xous-rs`
must have the same feature set.
This breaks them apart so the kernel can have one set of features and
programs can have another set.
As part of this change, tests are now integrated into the kernel, and a
new `create_process_as_thread()` and `wait_process_as_thread()` function
pair have been added.

The goal is to get a basic message passing engine working that will also
function as a device that works on real hardware.
This is still reworking it to function correctly on a desktop system.
Once that is working, it will be reworked to function once again on
hardware.
