Wildcard target dependencies

[fxposter]

I'd like to propose adding the ability for a target to depend on the dynamic amount of dependecies by specifying them like this:

{
  "targets": {
    "build-css": {},
    "build-js": {},
    "test": {
      "dependsOn": ["build-*"]
    },
  }
}

That would mean that target "test" depends on both "build-css" and "build-js".

I see two reasons for such feature to exist:

1. you will be able to define generic dependsOn for a project and plugins will be able to insert the targets that will run at particular steps without changing the project itself.
2. it would be possible to split that "build-css" from the example into 2 targets - "build-css-1" and "build-css-2", while not changing the test target, that would allow executing "build-css-1" and "build-css-2" in parallel without changing all the wiring and dependencies between targets.

I have made a PR a while ago that implements this behaviour and it is passing and actually was passing for months already (the only failures there were sporadic timeouts from time to time): #19611. The implementation is small and will unlikely cause any issues. In case of people not using such wildcards dependencies - the behaviour is exactly the same as the current one.
