Pull request overview

This PR adds support for the AUTOSAR SHE CMD_GET_ID command across the wolfHSM client/server messaging layer, exposing a client API to request module identity and implementing the server-side handler to return UID, status (SREG), and an identity CMAC.

Changes:

• Added WH_SHE_GET_ID to the SHE action enum and introduced GET_ID request/response message types plus translation helpers.
• Implemented client APIs (wh_Client_SheGetId*) and server handler (_GetId) including SREG composition refactoring via _BuildSreg.
• Added end-to-end and server-direct tests covering MAC verification, truncated request handling, empty MASTER_ECU_KEY fallback-to-zero-key behavior, and pre-secure-boot allowance; updated docs accordingly.
