Not possible to use Angular builders from local nx-plugin

[minijus]

Current Behavior

It is not possible to use Angular builder from workspace local nx-plugin:

• Defining builder (without "cli": "nx") fails with Cannot find module '@builder-repro/nx-plugin/package.json'
• Using executor (with "cli": "nx") with scheduleTarget fails with Cannot find module '@builder-repro/nx-plugin/package.json'
• Using executor to invoke builder directly is not possible because of lack of interoperability between nx ExecutorContext and Angular BuilderContext.

Expected Behavior

It would be great having possibility to invoke/execute Angular builders from local nx-plugin.

Steps to Reproduce

I've created fresh repository with all 3 scenarios reproduced: https://github.com/minijus/builder-repro. 3 executor targets are defined on test-app: https://github.com/minijus/builder-repro/blob/main/apps/test-app/project.json#L53-L88

It would be nice if the @nrwl/* executors consistently used the same context (Executor or Builder) for all tasks, rather than using ExecutorContext for most and BuilderContext for Angular tasks (even the nrwl/angular custom ones).
