This adds optional support for using OpenVPN3 client
as an alternative to openvpn2.
Just replacing one client with another will not work:
- OpenVPN3 doesn't use interactive service, it uses
"agent" service with completely different protocol. OpenVPN GUI
needs to talk to agent using HTTP and JSON.
- OpenVPN3 management interface realtime notifications must be
explicitly turned on in order for GUI to work.
To enable using openvpn3:
- use any of *-ovpn3 presets (cmake build system)
- ./configure --enable-ovpn3 (mingw)
To switch betweet openvpn2 and openvpn3, see "OpenVPN Engine"
radiobutton group in Settings -> Advanced dialog.
OnReady() implementation was slighly changed - "log all on"
replaced with "log on all" - according to management interface
documentation this is the right way to do it, and also OpenVPN3
only supports "on all" order.
Management interface - enabled OpenVPN3 client (omiclient.exe) and
agent (ovpnagent.exe) are now part of openvpn3 repo.

Ninja makes build slightly faster but requires running
"x64" developer command prompt, not the "default" one.
Without that, cmake silenly produces x86 binaries and it might
take a while to find out the reason. To avoid confusion, switch back
to MSVC generator.

Manifest is a convenient way to automatically
install dependencies. Since we have to support
both OpenSSL 1.1.1 (for OpenVPN 2.5) and OpenSSL 3
(for coming OpenVPN 2.6) and manifest file name
is hardcoded, we create two manifests and put them
into different directories.
To simplify build process, define configuration presets
for arch (x86/x64/arm64), debug/release and oss1.1.1/ossl3.
This way building is greatly simplified:
cmake -S . --preset x64-debug-ossl3
cmake --build --preset x64-debug-ossl3
Update GitHub Actions script accordingly.
