Add kernel MCTP (AF_MCTP) support and transport-implementation option

-Added support for kernel MCTP (AF_MCTP) to enable MCTP communication
using AF_MCTP sockets.

- Introduced a new configuration option 'transport-implementation'

The 'transport-implementation' option can be set to either:
- 'mctp-demux': Uses the existing mctp-demux transport method.
- 'af-mctp': Uses the new kernel AF_MCTP transport method.

clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.
See Iea0776aaa7edd483fa395e23de25ebf5a6288f71 for clang-18 enablement.

This change migrates the application off of the deprecated "requester"

We don't currently have the infrastructure in place to get the correct

Handle other PLDM_STATE_SET_OPERATIONAL states

- Code will no longer assume the OCC is not running if an unexpected
state is received. It will continue to look for a good/known state.
- Added code that will throttle the occ-control pldm journal traces
if unable to read the OCC active sensor states. In some error
conditions, this tracing would flood the trace and the repeated traces
are not helpful for debug.
- Change some journal entries to ERR when the state indicated that the
system was in safe mode (OCCs disabled)
- If request for occ active sensor state was sent, and then a PLDM
sensor event comes in for that instance, the event status is used and
the response is ignored.
- Added README for occ-control

Fix correlation between OCC StateSensorPDRs and procs

occ-control was not correlating the OCC Active sensors with the correct
processor. Code change will now use the Sensor ID to know which
OCC/proc is active. Hostboot will also be making a change to ensure that
the Sensor IDs are always numbered according to processor order (p0, p1,
etc)

Wait for PHYP to start before reading PLDM sensors:
occ-control caches the PLDM sensor IDs to limit the dbus queries.
The cache was supposed to be cleared when the OS was powered off, but
the existing code only cleared it when CurrentHostState was Off.
Got a defect where occ-control was using invalid/old sensor IDs when
getting notifications of OCC Active sensors. This causes the app to try
communicating with the wrong or invalid OCC.

Code change will clear the sensor cache anytime PHYP is not running, and
will populate the cache once PHYP is running.

Tested on hardware with various boot types and resets.

It will also read the OCC Active sensor to determine the state before
allowing communication.

When Hostboot moves a system to safe mode it will set the PLDM state of
the OCC Active sensor to PLDM_STATE_SET_OPERATIONAL_RUNNING_STATUS_DORMANT
This commit will also handle processing of that DORMANT status.

pldm: Add support for OCC state changes

When the state of the OCC changes, host sends stateSensorEvent to
indicate going active or not active which is send as a D-Bus signal
by PLDM daemon. openpower-occ-control app listens for this signal
and updates the OCC D-Bus object. The lowest entity instance number
in the PDRs corresponds to first instance of the OCC.

Tested:

1) On a simics session verified that the sensor event is handled for
OCC going active and OCCActive property is set to true.
2) A sensorEvent is generated for OCC going non active and verified
OCCActive property is set to false.
3) Powered off the host and OCCActive property is set to false.
