Previous attempt to fix git sha on non-git build broke git build. (#3322)
This uses unusual code provided by Mikhail Lopatkin of Gradle Inc:
https://github.com/gradle/gradle/issues/23914#issuecomment-1431909019
It wraps the git sha function in a "value source". This allows it to interact correctly with configuration caching.
Because the code is longer than before, it is now broken out into its own file getGitSha.gradle.
