Adds a `module.isPreloading` property that is `true` only during the preload (`-r`) phase of Node.js bootstrap. This provides modules an easy, non-hacky way of knowing if they are being loaded during preload.

It might be a good idea to also backport NativeModule.prototype.isPreloading:
node/lib/internal/modules/cjs/loader.js

Backport of #36263 and #36944.
Note that #36944 hasn't been released on a Current line for two weeks, but fixes a documentation bug which should land alongside #36263 IMHO.
