Create module hash for each module in SGX lib-rats (#1745)

Browse Source 
Current SGX lib-rats wasm module hash is stored in a global buffer,
which may be overwritten if there are multiple wasm module loadings.
We move the module hash into the enclave module to resolve the issue.

And rename the SGX_IPFS macro/variable in Makefile and Enclave.edl to
make the code more consistent.

And refine the sgx-ra sample document.
