Enable interop for scala.js (zio#28)

* Enable interop for scala.js

  * Test more thoroughly
  * Delete `Alternative` instance (unlawful)
  * Simplify some method implementations

* Disable failing cats-effect laws for the time being

  * `bracketReleaseIsCalledOnCompletedOrError`
  * `runCancelableIsSynchronous`

* Add a test for summoning Monad[UIO]

* Define maximum memory limit in .jvmopts

* Increase no_output_timeout for scala.js on 2.13

* Override runCancelableIsSynchronous

* override bracketReleaseIsCalledOnCompletedOrError (replace F.pure(b) with fa.attempt.as(b))

* Silence errors from runCancelable/runAsync same as cats-IO impl does. (unsafeRunAsyncAndForget logs errors via EC)

* Further bump JVM limits in .jvmopts

* Further bump JVM limits

* Fix cause of flaky equality – zipPar is not deterministic; replace genParallel by ZManaged.fork-based version; split out shared test implicits; re-add repeat tests for ApplicativeLocal & ConcurrentEffect

* inherit AnyFunSuite directly in test base

* fix build

* remove test loops

* decrease heap to 4G

* duplicate .jvmopts in .sbtopts

* remove redundant .jvmopts
