In order for OpenOCD to have a high-level view of an RTOS, it uses the GDB protocol to obtain symbols from the system. The GDB protocol, however, does not allow obtaining fields from structures directly, and hardcoding offsets is not only brittle (due to possibly different architectures or changes in the code), it's also infeasible considering Zephyr is highly-configurable and parts of key structs can be compiled in or out. Export an array with offsets for these key structs. Also add a version element in that array to allow changes in those structs.
