[bazel] validate packages/BUILD.bazel in CI

[spalger]

With #127095 we started generating the packages/BUILD.bazel file. This only happens when you generate a new package though, and can cause unexpected updates when a user generates a package after others have manually updated the file.

To ensure that this file is always up-to-date with the state of the repo and sorted correctly this PR adds node scripts/generate packages_build_manifest. This new command just regenerates the packages/BUILD.bazel file based on the packages discovered. This command also supports a --validate flag which will be run on CI to fail CI when the file is outdated:

Additionally, this PR fixes a bug with the default @npm// deps includes in generated BUILD.bazel file that @clintandrewhall caught as he experimented with this new generator, improves the help text for the --web option.

On Windows this replaces all packages from //packages/ -> //packages\

Thanks @jbudz, paths are annoying but I think I've fixed this.
