Refactor git_repository and new_git_repository rules implementations ?

?so that they can be used with Bazel on Windows without MSYS

- do not use shell scripting, call git binary and use repository_context methods
- add black box tests for new_git_repository, so that they run on Windows without MSYS
- prefer fetch to clone, as in that case less content is fetched (with fetch, we specify both the reference and depth in the same command; on contrary, clone will fetch all branches)

Closes #8677.
