Add ioctl command logic for enclave VM creation. It triggers a slot

it will be used as an identifier for triggering enclave run.
Return a file descriptor, namely enclave fd. This is further used by the
associated user space enclave process to set enclave resources and
trigger enclave termination.
The poll function is implemented in order to notify the enclave process
when an enclave exits without a specific enclave termination command
trigger e.g. when an enclave crashes.

Again, if a file operation does nothing, don't even provide it.
I removed open() in v3.
Thank you.
