The "git.rc" is used on Windows to embed information like the project
name and version into the resulting executables. As such we need to
inject the version information, which we do by using preprocessor
defines. The logic to do so is non-trivial and needs to be kept in sync
with the different build systems.
Refactor the logic so that we generate "git.rc" via `GIT-VERSION-GEN`.
