protobuf3-cpp: Update to newer version

[ryandesign (Ryan Carsten Schmidt)]

MacPorts protobuf3-cpp is at version 3.19.3 which is from January 2022.

3.23.1 was released in May 2023:

% port livecheck protobuf3-cpp
protobuf3-cpp seems to have been updated (port version: 3.19.3, new version: 23.1)

livecheck needs to be adjusted to account for their ​new version numbering strategy (limit livecheck to 3.x versions).

I just had look at this.

The build system is severely broken

1. libraries are built into build, but at link time it is looking for them in build/../lib

2. The abseil-cpp submodule doesn't seem to build any libraries, and there is no way of pointing at the existing abseil port which contains the required libs.

I'm attaching the WIP Portfile

It looks like both FreeBSD and Homebrew are using the last autotools version of protobuf3-cpp: 3.21.12. Versions (3).22.x and (3).23.x use cmake and are both a terrible mess.
