While we were debugging performance problems last year, we introduced `managerType: 'xs-worker-no-gc'`, which is a variant of `xs-worker` that disables the forced GC we were doing at the end of every delivery. Since then, we've improved performance in several ways: * XS bugs were retaining objects, which have since been fixed * we only do a forced GC during special `dispatch.bringOutYourDead` cranks * we deliver BOYD less often (according to a configurable schedule, see #4160 for our decisions, but we're thinking once every 100 to 1000 deliveries) The `xs-worker-no-gc` manager type controlled a flag named `gcEveryCrank`, which replaced the GC primitive available to liveslots with a dummy version. This commit removes both `xs-worker-no-gc` and `gcEveryCrank`. closes #5600
