Providing `nodeExecCommand` setting

[sjrd]

This is something that can be done with a custom NodeJSEnv.Config:

import org.scalajs.jsenv.nodejs.NodeJSEnv

jsEnv := {
  new NodeJSEnv(NodeJSEnv.Config()
    .withExecutable("nvs")
    .withArgs(List("exec", ver)))
}

When suggesting this I mainly had interactions with Webpack in mind:

• scalajs-bundler/sbt-scalajs-bundler/src/main/scala/scalajsbundler/Webpack.scala

  Line 285 in d083e6d

  val cmd = "node" +: params

• scalajs-bundler/sbt-scalajs-bundler/src/main/scala/scalajsbundler/WebpackDevServer.scala

  Line 54 in d083e6d

  "node",

  
  It is not possible to intercept node executable used for them.

Wouldn't that be possible to do in user space using #420, then?

No, because that PR does not expose these bundler related node invocations that I have linked above. New setting is the only way. Do not see a problem here - it is a beneficial change that is easily backwards compatible.
