Propagate the ProcessManagerError enum through the
PackageManagementInterface and ProcessControlInterface so the client
has more information about why a request failed.

Now that logger level is passed with the message it can be added on the
server side if desired. For now just remove it entirely so we have more
space for the actual message.

Components can reduce the number of rpc's if they set_max_level but by
default pass everything and let the DebugConsole decide what is logged.
With this the shell loglevel command now controls logging from all
components.

This ends the behavior where log messages would block on the prompt.
This change does not fix the potential race on dataports if
kata-uart-client read or write has multiple concurrent callers. A later
change will protect those using CAmkES mutexes, although the
alternative of having DebugConsole *own* the UART should also be
considered.

Add a VectorCoreDriver component that handles setting vector core CSRs.
Rewrite MLCoordinator to conform to other Kata components. The old code
wasn't useful.
Add `test_mlexecute` command for running ML. Add plumbing from shell to
coordinator.

- Split support into three levels:
o kata_proc_manager::process_manager is a single-threaded implementation
of ProcessManagerInterface and PackageManagerInterface that uses an
abstract manager interface to carry out low-level work (used mainly
to inject fakes for unit testing).
o kata_proc_manager is a thread-safe wrapper around process_manager that
has the manager interfaces bound to KataOS; this is the level at which
we integrate with external components.
o kata_proc_component is the top-level glue code for the ProcessManager
camkes component; it has a pre_init function to setup rust support
(logger, allocator, etc), a run function for the component's control
block, and wrapper functions for the camkes ProcessControl and
PackageManagement interfaces.
- Add install, uninstall, start, stop, and bundles shell commands for
exercising ProcessControlInterface & PackageManagementInterface.
Specifics:
- Bundle id's are now treated internally as SmallString's with &str
used for passing bundle id's through api's. The BundleId type is
temporarily used for get_running_bundles() to return information (but
see below about RawBundleIdData).
- ArrayVec's are replaced with a hashbrown::HashMap
- Bundle objects are Box'd instead of holding refs (now that we have an
allocator); this eliminates lifetime constraints.
- The manager interface is Box'd to eliminate lifetime constraints.
- Purge ProcessManager::empty(), it's infeasible with the hashmap and
is not needed with kata_proc_manager support for static decls.
- Add RawBundleIdData support for serialize+deserialize of BundleIdArray;
no more leaking internal data types to client code.
- Remove bounds check on #bundles recorded; set a nominal capacity
and fallback to dynamic allocation of the hashmap.
- Manually update ProcessManagerBindings.h (using cbindgen).

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 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.

- 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

ML Coordinator needs to be able to load and unload models, which means verifying
and creating any necessary transfer buffers and other data structures.
