8b7c33c565 SDKRuntime: add key-val store api's

d0d46c89e1 SDKRuntime: plumb application access
Setup a connection to the SDKRuntime for each application. To do this
add an SDKManager interface to the SDKRuntime for the ProcessManager to
obtain a badged endpoint and install that in each application's CNode.
SDKRuntime now rejects requests received without a registered badge.

RPC's are handled entirely in Rust (no CAmkES). ProcessManager sets up
RPC resources and delivers them to an application through registers.
The application-side SDK runtime uses the resources to marshal RPC
parameters in a page that is attached to the IPC buffer sent to the
SDKRuntime. Reply parameters are written to the shared page and decoded
on return.

Overhaul the SDKRuntime api to be like SecurityCoordinator to consolidate
parameter marhsaling/unmarshaling and to simplify adding new methods.

Rust applications use the SDKRuntime interface directly. C application
will wrap a C interface around the Rust impl (TBD).

Specific changes:
- add SDKManagerInterface
- sel4bundle now plumbs a connection to the SDKRuntime, the CNode slot
  with the capability is passed to the application to future-proof CNode
  setup changes (an alternative is to use a global const since we control
  the application-side runtime api's)
- add kata-sdk-manager crate with SDKManager client interface support;
  the only api's are get_endpoint (to get a badged endpoint to SDKRuntime),
  release_endpoint (to remove a badged endpoint), and capscan (to dump
  the SDKRuntime's top-level CNode)
- add "capscan sdk" in the shell to inspect the SDKRuntime service
- make SDKRuntime require a registered badge on inbound IPCs
- fill-in ping & log SDK api's
- connect ProcessManager to SDKRuntime for SDKManager api use,
  everything else happens outside CAmkES
- make SDKRuntime lock against concurrent requests--the SDKManager
  runs concurrently and shares SDKRuntime state
- remove kata-shell test_sdk_* commands (replaced by test applications)

b099005951 kata-os-logger: support no logging interface connection out of a component
When a CAmkES component lacks an outbound connection to send log msgs
there will be no logger_log symbol. Use a weak ref here to handle that
without resorting to a feature or similar.

Mark logger connections as "maybe" so they are optional.
