Run gen-versioninfo unconditionally (#8368)

This fixes an issue where the output of `--show-config` would not be updated properly in certain cases (e.g., when files were modified but cmake is not run). We now run the `gen-versioninfo` target unconditionally, always updating the `versioninfo.cpp` where the version data for `--show-config` is stored.
