Fixes the CreateObject service list-of-initial-values encoding and decoding by refactoring the data structure to be similar to WriteProperty. The implementation changes from using a linked list of property values to using a flat buffer approach with delayed decoding.
Changes:
* Refactored BACNET_CREATE_OBJECT_DATA structure to use an application_data buffer instead of a linked list for initial values
* Added a new create_object_process() and create_object_initializer_list_process() functions to centralize object creation logic and error reporting
* Updated all device implementations to use the new centralized creation functions
* Enhanced the create-object example application to support command-line specification of initial property values
* Added comprehensive test coverage for the new encoding/decoding and processing functions
* Added ListElement service callback for storing data.
* Added Audit Log and Time Value objects to basic device.
* Added Audit Log object to Makefile and CMake builds.
* Added basic timer object, internal state machine, and unit tests
* Added BACnetTimerStateChangeValue encode, decode, parse, print, and diff with unit tests
* Changed handler of add/remove list element to check if the property is a BACnetLIST
* Added BACnetLIST utility for handling WriteProperty to a list.
* Fixed outlier ReadProperty object handlers to return zero when the RP parameter is NULL.
* Added Device_Object_Functions_Find() API to enable override of basic object API function.
* Added Device_Object_Functions() API to return basic object API table of functions for all objects.
* Converted device object test to use common read-write property test. Extended the basic BACnet device object example API.
* Created BACnet/IP and COV test mocks to enable device object testing with less dependencies.
* Added missing API defined in header into ports/win32/dlmstp.c module, added a PDU queue and refactored receive thread, and refactored MS/TP timing parameters.
* Added missing API defined in header into ports/linux/dlmstp.c module, and refactored MS/TP timing parameters.
* Added missing API defined in header into ports/bsd/dlmstp.c module, and refactored MS/TP timing parameters.
* Reduce default MS/TP APDU to 480 to avoid extended frames by default.
