This change adds an "rz" command to the shell that calls a function
rz(). It switches the IO from the shell to a ZMODEM receiver that
produces a Rust upload object that collects the uploaded bytes and
computes a CRC32 checksum on the fly.
In a later change, we will retain the most recent payload in a
shell-owned object until it is consumed by an "install" command.
Limitations:
* Sender hangup will cause the receiver to block forever and the
prompt not to come back, since kata-uart-client does reads that
block forever.
* Logging must be set to a level higher than debug or messages from
the zmodem crate itself corrupt the transfer.
* The sender must rate limit to ~150 bytes/sec to avoid running
too far ahead of the Renode UART, which drops bytes when the RX
FIFO is full.
* Uploading too big a payload will cause a kata_panic! unless the
heap size is increased in kata-debug-console/src/run.rs

Kata OS
This is a CAmkES project that assembles the entire Kata OS. It exists outside the seL4 source trees, since it contains code not intended to go to upstream seL4.
This uses the standard CAmkES build system by symlinking CMakeLists.txt. It also symlinks settings.cmake, and so retains the notion of "apps," which enables the build system to switch which assembly it builds using the CAMKES_APP CMake cache value. Kata OS just has one app, system.
