Introduce the main thread and HECI Active Management (HAM) message handling for the ISSEI (Intel Silicon Security Engine Interface) subsystem. The main thread is responsible for managing the reset flow and processing messages, while the HAM message handling is crucial for initializing communication with the firmware and managing clients. With this implementation, the ISSEI driver is capable of performing the required initialization and management of communication between the host and the firmware.
