Genericized (was test.check specific) compiler changes for downstream macro/ns resolution

[willcohen]

Reopening as followup to #803, which autoclosed when #802 merged. Needed for squint-cljs/cherry#184, which I similarly need to rebase and re-open based on this.

Please answer the following questions and leave the below in as part of your PR.

• This PR corresponds to an issue with a clear problem statement.

• This PR contains a test to prevent against future regressions

• I have updated the CHANGELOG.md file with a description of the addressed issue.

Eep. Stuff still changing underneath. This can happen later.

Hehe sorry. I wasn't done with cljs.test but it's published now and no changes planned.

[willcohen]

@borkdude this is now ready — took a little finagling after cljs.test settled. One more small proposed change to macros. I needed this for test.check because defspec bodies carry (prop/for-all …) aliased (not :refer'd), so without this the macro never fired: the compiled JS emitted a raw prop.for_all(…) runtime call, which was causing undefined errors.

Rebased to sit on top of latest changes to squint. squint-cljs/cherry#186 updated as well.

[borkdude]

I'm not yet sure about this approach. clojure.test is a built-in namespace but clojure.test.check is an external dependency in ClojureScript so I don't think this change belongs in squint.

[willcohen]

Makes sense. I'll give it a shot.

[willcohen]

Here's a lighter touch approach to squint. I dropped the test.check specific stuff here, and cherry now handles that via env.

Three new commits:

First: "Populate :macro-aliases from :require :as so plain require finds built-in macros". Same content as before, rebased onto current main.
Second (new): "Make :cherry target of resolve-ns honor :resolve-ns env hook for symmetry with :squint". Cherry was already passing :resolve-ns from cli.cljs, just unused on the :cherry path.
Third (also new): "Filter :refer'd macros via env-supplied :built-in-macro-nss". Adds an inline env hook in the :refer filter so downstream targets register their own macro names without squint knowing about them.

[willcohen]

To better decouple this from the various cherry PRs that depend on it, I've added red/green tests preceding each of the three commits, which should allow this to be self-contained. @borkdude

Merged main in so this now applies cleanly after #816.
