This includes adding it to TOML files and CAmkES assembly files.

This CL handles the integration of the Image Manager, which comes
concurrent with the necessary WMMU changes needed by the Image Manager.
The ML Coordinator now calls into Image Manager to make space, commit
images, and set the WMMU.
The MlCoordinator now first verifies that an image is valid by first making a pass through the section headers. It stores the two sizes that we're interested in per image: how big it is packed on flash, and how big it is unpacked in memory.
Known issues:
b/241799340: Refactor BundleImage to support unit testing
The writes to DMEM via the kata-vec-core crate was meant to be in image_manager.rs, but this interfered with the ability to run unit tests. We can refactor BundleImage to make this work.
b/241799866: Improve heap management
Right now I clear all of the "temporary data section" (bss, stack,
heap), but I suspect only the heap needs to be cleared. This needs more effort to check that that's correct, and track those locations.
Minor changes:
ImageId is used instead of (String, String) in the component.

Add support to output the contents of the top-level CNode of a CAmkES
service or KataOS application to the serial console. This is dependent
on kernel support that is enabled with CONFIG_PRINTING. Applications
must be running; otherwise there is no CSpace to dump.
Specific changes:
- add a "capscan" shell command
- add capscan method to each CAmkES interface
- add capscan_bundle method to the ProcessControlInterface
- add Camkes::capscan() to dump the top-level CNode
- add ProcessManager support to dump the CNode for a bundle

Add a new "camkes" submodule that consolidates KataOS CAmkES component
integration boilerplate. Each component is expected to declare:
static mut CAMKES: Camkes = Camkes::new("ProcessManager");
and then (typically) use "pre_init" to setup the logger, heap, and the
slot allocator. More fine-grained control is provided by:
fn init_logger(self: &Cmakes, level: Log::LevelFilter);
fn init_allocator(self: &Camkes, heap: &'static mut [u8]);
fn init_slot_allocator(self: &Camkes, first_slot: seL4_CPtr, last_slot: seL4_CPtr);
When receiving capabilities use "init_recv_path" to setup the IPCBuffer
receive path and "assert_recv_path" & "check_recv_path" calls to verify
noting has clobbered the setting.
The debug_assert_slot_* macros are wrapped in Camkes:: functions and a
"top_level_path" function for constructing seL4_CPath objects. Altogether
this normally allows a component to be written without direct use of the
CAmkES global static identifiers SELF_CNODE*.

This CL enables multiple outstanding periodic executions. To do so the
MlCoordinator now includes an array of started models and a queue of
models that are ready to be executed immediately. Additionally, each
periodic model has an associated timer. When that timer fires the model
is added to the execution queue. When a model finishes executing, the
next model is popped off the queue and executed. If a model becomes
ready when there's already an execution for it queued, that execution
is dropped and a warning printed. A cancel command is added to remove
periodic or outstanding executions.
A state debug command was also added.
Currently we can only load a single model due to limitations with the
StorageManager, but we can do so multiple times.
