build: update to more improved copy_to_bin rule.

This is necessary as the current rule is not clever enough to detect
when a given file is already "generated" and inside `bin`.

This is important because `package.json` files are always copied to bin
for `npm_package`, but the `package.json` may already be copied from
e.g. `ts_project#data`. This shouldn't cause a Bazel action conflict.
