wasi-sockets: TCP connect from a Bound state.

[pavelsavara]

__wasi_sockets_utils__map_error is missing conversion for NETWORK_ERROR_CODE_INVALID_STATE for connect in wasi:socket

Test case

TcpClientSocket_WhenBoundToWildcardAddress_LocalEPChangeToSpecificOnConnect

Place to fix

INVALID_STATE is already mapped:

	case NETWORK_ERROR_CODE_INVALID_STATE:
	case NETWORK_ERROR_CODE_NOT_IN_PROGRESS:
		abort(); // If our internal state checks are working right, these errors should never show up.
		break;

Given that wasi-libc correctly follows the state diagram this behavior is the correct thing to do, IMO.

It's wasmtime that's at fault here. It (and every other engine) should either:

• support connecting from a bound state (the preferred option of course), or:
• return error-code::not-supported if it doesn't support connecting from a bound state.
