Intel-SIG: commit 41493a09 selftests/sgx: Provide per-op parameter
structs for the test enclave.
Backport for SGX EDMM support.

--------------------------------

To add more operations to the test enclave, the protocol needs to allow
to have operations with varying parameters. Create a separate parameter
struct for each existing operation, with the shared parameters in struct
encl_op_header.
