* CI: Port Windows build to Azure Pipelines from Appveyor
* CI: Split Windows build into scripts
* CI: Remove Appveyor
* CI: Add GitHub Release deployment to Azure Windows Build
* VCS: Add full branch name function to rpcs3_version
The STRINGIZE macro was a little awkward, and difficult to control
at configure time. Since other version information is already
included, the full branch name is now added as a function. It's
runtime instead of compile-time checking, but it seems worth it.
* CI: Overhaul Windows setup script
Previously, there was no way of forcing a re-download
of cached dependencies when they were replaced by new ones. In
addition, there was really no verification of downloads or cache.
Now, changing a few lines at the top of the file will automagically
force a cache update.
