[PATCH v17 14/23] x86/sgx: Add wrappers for ENCLS leaf functions

ENCLS is an umbrella instruction for a variety of cpl0 SGX functions. The ENCLS function that is executed is specified in EAX, with each function potentially having more leaf-specific operands beyond EAX. ENCLS introduces its own (positive value) error codes that (some) leafs use to return failure
