Mutex<Heap>::lock() gives inner mutability so ditch the RefCell that came
from the original Cortex-M code.

The preboot code still sends kernel logging to the 16550. A later change
will also port this to OpenTitan or find another alternative.

- the RELEASE setting is a boolean, correct cmake check
- explicitly force log-level=0 & debug=true in cargo profile.dev entries
NB: to switch between RELEASE + non-RELEASE builds do "m clean",
change easy-settings.cmake, then "m kata"

Sprinkle seL4_Yield's in the tx/rx polling loops so other work in the
DebugConsole component happens. This is a band-aid for the driver not
using interrupts.

Replace LockedHeap with a purpose-built equivalent. This works around
issues where rust_oom was undefined for certain build configs and
facilitates future sel4 integration (e.g. to use dynamically allocated
memory instead of bss).

- add a linked_list_allocator::LockedHeap instance to each component that
might want to allocate memory and init the allocator with a fixed-size
memory block in the component post_init hook
- add an alloc_test shell command that exercises the allocator
This does not dynamically add memory or support sharing memory between
components; this is an intermediate step to simplify bringing in crates
that want to allocate memory (e.g. hashbrown)..

To write s3L4 for OpenTitan matcha, we want to depend on generated C
header files for definitions of MMIO sizes, offsets, masks, bit
meanings, etc.
To make these header files available to the seL4 build, this change adds
a make prerequisite for the kata build to run regtool.py with output
going to out/kata/opentitan-gen.
In CAmkES CMake files, the INCLUDE attribute can be used to add to the
include path, and this change also does that for the UartDriver
component. (The implementation will be left for a later change, since an
initial straighforwrd attempt saw writes still going to the 16550.)

This only serves to confuse the cmake build tools into using the wrong
definitions, instead of the ones used in apps/system/rust.cmake.

This turns on "fat" LTO for builds even in dev mode so that we can keep our
binaries size down. It's not a total solution, but eliminates the "kitchen sink"
effect that building Rust static libs has, allowing us to keep our dependencies
down a bit.

- new ProcessManager component (aka kata-process-manager)
NB: interfaces/ProcessManagerBindings.h is manually generated by cbindgen
for the moment; e.g.
cargo install cbindgen;
cd components/ProcessManager; cbindgen -c cbindgen.toml \
-o ../../interfaces/ProcessManagerBindings.h kata-proc-common

- add a SeL4Debug component that wraps seL4DebugPutString and seL4DumpScheduler
system calls that are marked static inline (so not callable from rust)
- connect seL4Debug to the DebugConsole and add a "ps" command to the shell
that uses sel4DumpScheduler to print the tcb's on the console; e.g.
KATA_PROMPT> ps
Dumping all tcbs!

ML Coordinator needs to be able to load and unload models, which means verifying
and creating any necessary transfer buffers and other data structures.
First draft just keeps track of model references.
ML Coordinator needs to be able to execute models. Actual execution is
abstracted away from ExecutiveInterface.
Deletes fake_executive and moves to this file in the test section, as
this is currently the only user.

Create some common data types and a fake executive. The fake executive
can either return an error (emulating execution failing) or a slice of
memory (emulating a correct result).
