A rule that copies source files to the output tree.
This rule uses a Bash command (diff) on Linux/macOS/non-Windows, and a cmd.exe command (fc.exe) on Windows (no Bash is required).

copy_to_bin(name, srcs, kwargs)
Copies a source file to output tree at the same workspace-relative path.
e.g. <execroot>/path/to/file -> <execroot>/bazel-out/<platform>/bin/path/to/file
If a file passed in is already in the output tree is then it is added directly to the DefaultInfo provided by the rule without a copy.
This is useful to populate the output folder with all files needed at runtime, even those which aren't outputs of a Bazel rule.
This way you can run a binary in the output folder (execroot or runfiles_root) without that program needing to rely on a runfiles helper library or be aware that files are divided between the source tree and the output tree.
