[roll] Roll third_party/fuchsia-infra-bazel-rules [bzlmod] Migrate some non-fuchsia dependencies.

Migrates @bazel_skylib and @rules_python from WORKSPACE to bzlmod.

This change also removes @platforms and @host_platforms, since it seems
they are no longer needed.

The rest of the dependencies seem to be intertwined fuchsia
dependencies, and may be simplified if @rules_fuchsia was adjusted to
declare its own MODULE.bazel and/or module extensions.
