Implement Berkeley Socket API for Intel SGX (#1061)

Browse Source 
Implement Berkeley Socket API for Intel SGX
- bring Berkeley socket API in Intel SGX enclaves,
- adapt the documentation of the socket API to mention Intel SGX enclaves,
- adapt _iwasm_ in the mini-product _linux-sgx_ to support the same option as the one for _linux_,
- tested on the socket sample as provided by WAMR (the TCP client/server).
