This PR adds two new rules: copy_file and copy_xfile. Both rules solve a common problem: to copy one file to another location. The problem is routinely solved using a genrule. That however requires Bash, since genrules execute Bash commands. Requiring Bash is a problem on Windows. The new rules do not require Bash on Windows (only on other platforms). The only difference between the rules is that copy_xfile creates an executable file while copy_file doesn't. See https://github.com/bazelbuild/bazel/issues/4319
