feat(builtin): expose @npm//foo__all_files filegroup that includes …
Browse files Browse the repository at this point in the history 
…all files in the npm package

Including files with spaces & unicode characters & files that have been filtered out by the `included_files` attribute. This filegroup cannot be used in runfiles because of Bazel issue bazelbuild/bazel#4327, but it can be used for other purposes such as the srcs input to a pkg_tar for generating a tar of an npm package pulled down with yarn_install or npm_install.
