build: add a version build-tag for non-release builds (#156)
The build tag can be set during the build (using either the Makefile or the CMake). If it's not provided, and we're not in a release build, it will be calculated using the state of the git tree since the last release tag (for example, for this PR the build tag will be calculated as `(main+17)-(156-build-add-a-build-tag-into-the-version-for-non-release-builds+1)`. If the git tree state can not be determined, a question mark will be used instead.
