Struct IgvmSignal 

pub struct IgvmSignal(/* private fields */);

Bitmap indicates a signal to requestor 0 - IGVM_SIGNAL_RETRY_RECOMMENDED_BIT: Retry recommendation 1 - IGVM_SIGNAL_SKIP_HW_UNSEALING_RECOMMENDED_BIT: Skip hardware unsealing 2 - IGVM_SIGNAL_RSA_AES_KEY_WRAP_384_USED_BIT: Set by the IGVM Agent to indicate that the agent asked AKV for the SHA-384 variant (RSA_AES_KEY_WRAP_384) and AKV used it to wrap the key in the payload. If this bit is clear, AKV wrapped the key with the default CKM_RSA_AES_KEY_WRAP scheme (inner RSA-OAEP using SHA-1). 3 - IGVM_SIGNAL_CORIM_ENDORSEMENT_REQUESTED_BIT: Set by the IGVM Agent to indicate that the agent requested the CoRIM endorsement.
