Disable RCF in the JVM during CLJS build (in :require-macros scenario)

[dustingetz]

When the CLJ REPL and Shadow are sharing JVM, RCF tests are enabled at the CLJ repl and Shadow needs to disable JVM RCF tests during incremental builds because :require-macros in a CLJS file will cause the CLJ files to load, running tests if enabled.

https://shadow-cljs.github.io/docs/UsersGuide.html#compile-stages

(defn rcf-shadow-hook 
  {:shadow.build/stage #{:configure :flush}}
  [build-state & args]
  (case (:shadow.build/stage build-state)
    :configure (enable! false)
    :flush (enable!))
  build-state)
