UEFI 2.5 specifices TLS protocol. I know this isn't really an answer, but
you could just wait for it to be implemented in edk2. Not sure when that
will be, but hopefully soon.
If you need it now, you might consider assigned/defining the network
functions in openssl (in the BIO struct if I remember correctly?) to custom
wrappers around the appropriate edk2 network stack functions. No need for
StdLib, but will require a bit of coding to get working.
