feat(angular): disable ngcc when not needed

[bovandersteene]

Issue:

What I did

If you run postInstall ngcc, you don't have to run it every time you start a storybook instance.
If you have a monorepo project with a lot of storybook settings and tests, this can cause lockouts and a message like this: “Another process, with id 5197, is currently running ngcc.”
We're adding an optional parameter to the angular configuration to disable ngcc. Ngcc is enabled by default

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?

If your answer is yes to any of these, please make sure to include it in your PR.

This thread also discusses why ngcc is run synchronously by Storybook: https://github.com/storybookjs/storybook/pull/11157/files#r591235103

Thanks for the PR! This totally makes sense

I left some comments 🙂

@ndelangen and @kroeder: Contributing to Storybook is such a great experience 💯 . Thank you for the quick follow-up 🙌🏻 . We will definitely do that again if we have the opportunity 😍

Would it be possible to patch this into storybook v6, since vNext is not yet released?

[ndelangen]

@DanielRose I recommend trying the beta release 👍

[DanielRose]

@ndelangen I'm sorry, but I'm not going to deploy a beta release on a production system.

Hi @DanielRose ,
I still get the ngcc error with beta version


I reproduce with compose:storybook, I use refs with url of my others storybook

Maybe another idea ?
