Revert "std.testing: add writeZigFile for TmpDir"

This reverts commit 7f13f5cd5f5a518638b15d7225eae2d88ec1efb5.

I'd like to review this one before it goes in. This is an awfully
specific API that I don't think belongs in std.testing. Also I don't
want any code snippets in doc strings. We have doctests for that.
