target/i386: Add SGX aex-notify and EDECCSSA support
The new SGX Asynchronous Exit (AEX) notification mechanism (AEX-notify) allows one enclave to receive a notification in the ERESUME after the enclave exit due to an AEX. EDECCSSA is a new SGX user leaf function (ENCLU[EDECCSSA]) to facilitate the AEX notification handling. Whether the hardware supports to create enclave with AEX-notify support is enumerated via CPUID.(EAX=0x12,ECX=0x1):EAX[10]. The new EDECCSSA user leaf function is enumerated via CPUID.(EAX=0x12,ECX=0x0):EAX[11]. Add support to allow to expose the new SGX AEX-notify feature and the new EDECCSSA user leaf function to KVM guest.
