Update bzl_library targets (bazelbuild#482)

* Pin rules_proto to a rev that contains bzl_library definitions

* Update bzl_library targets

Mostly so depending on them from a stardoc rule works now we load rules_proto

Mostly autogenerated & then tweaked based on the gazelle in bazelbuild/bazel-skylib#271

* Revert removal of for_bazel_tests filegroup target

* Update internal bzl_libraries to only be visible to //swift:__subpackages__

* Also limit visibility of //test/fixtures:common
