Asterius integration

[ylecornec]

Now that the initial support for asterius is merged, here is an issue to track things that are not working yet.

• No stardoc for asterius rules.
  Because of the following issue: //:bzl is currently broken in release archives bazel-contrib/rules_nodejs#2874.
  And for now stardoc always try to explore third party dependencies Do not require access to dependencies that aren't being documented bazelbuild/stardoc#93.

• haskell_module integration.
  See PR Revert "remove asterius tests using haskell_modules" #1629 which contains the asterius tests using the haskell_module rule.

• We use an hardcoded list of toolchain libraries for the cabal rules, so they may fail if we depend on toolchain libraries provided by ghc but not asterius.

• //tests/haskell_cabal_package
  This test imports its main function from Lib, and it is not visible as such in the asterius generated javascript files. This example also fails when calling ahc-cabal directly.

• //tests/binary_with_main
  This test is a bit similar because it makes use of the main_function attribute.

• The asterius bundle should be generated by asterius CI, and (if possible) for other platforms than Linux.

• When C interrop is supported by asterius, it should be tested here.

Closing, since asterius is deprecated and we don't plan to work on it further.
