feat(@angular-devkit/build-angular): add crossorigin options

[alan-agius4]

This options allows to define the crossorigin attribute setting of elements that provide CORS support

By default we set the value to anonymous.

Closes #14743

@alan-agius4 - Needs rebase

[vikerman]

What is the documentation impact for this change?

Also are we adding crossorigin="anonymous" by default? Is that necessary?

[alan-agius4]

Documentation in AIO will be auto generated when new options are added. ( from JSON Help)

With regards if we should always add it or not maybe we should discuss it further, and see if we should add a none option, as truth to be told it’s not really always necessary.

Of note is that crossorigin="anonymous" on a script element only has an effect on error reporting within the browser. (ref: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script)

Discussed and opted to use none.
