gpg4libre: cleanup gpgme & add gbuild lib for gpgmepp

This moves the external to gpgmepp, since that's what we _actually_
link against; plus tons of enablement for Windows build, mostly
related to linker probs integration.

There's still no good way to build a DLL with autotools, so we fall
back to gbuild manual make, see also tdf#91480
