feat(core): drop support for zone.js 0.10.x

[alan-agius4]

With this change we drop support for zone.js 0.10.x.
This is needed because in version 12 the CLI will only work with ~0.11.4. See angular/angular-cli#20034.

BREAKING CHANGE:

Minimum supported zone.js version is 0.11.4

[gkalpak]

Yay 🎉

I still see some occurrences of zone.js/dist/... (mostly in error messages and docs. They should also be updated, right?

• aio/content/guide/testing-components-scenarios.md
• dev-infra/BUILD.bazel
• packages/core/src/testability/testability.ts
• packages/core/testing/src/async.ts
• packages/localize/schematics/ng-add/index_spec.ts
• packages/zone.js/MODULE.md
• packages/zone.js/NON_STANDARD_APIS.md
• packages/zone.js/README.md
• packages/zone.js/lib/zone-spec/async-test.ts
• packages/zone.js/lib/zone-spec/fake-async-test.ts

Also, I think we should add the zone.js/plugins/ directory in .github/angular-robot.yml:

angular/.github/angular-robot.yml

Lines 76 to 80 in 838e3bd

	- "packages/zone.js/*"
	- "packages/zone.js/dist/**"
	- "packages/zone.js/doc/**"
	- "packages/zone.js/example/**"
	- "packages/zone.js/scripts/**"

I accept that some (or maybe all) of these changes are not directly related to this PR (and should have happened independently). I am bringing them up as you seem to have made similar changes in other places as part of this PR, but happy to captrure them in an issue to make them in a new PR (also happy to take them on).

BTW, there are some minor typos in the commit messages:

• One of the commits says "Minimum supported zone.js version is 0.11.1", but based on the changes in packages/core/package.json, it seems that 0.11.3 is the minimum required version. Do I miss something?

• -This is needed because in version 12. The CLI will only work with 0.11.x. angular/angular-cli#20034
  +This is needed because in version 12 the CLI will only work with 0.11.x. See angular/angular-cli#20034.

• -In CLI version 12, the old style of imports are no longer supported.

• zone.js incosistently appearing both wrapped in backticks and unwrapped 😁
• Some trailing periods are missing 😁

Thanks for the review @gkalpak. I can definitely that the other suggest changes.

Let me get back to this PR on Monday.

[JiaLiPassion]

@alan-agius4 , since zone.js 0.11.1~0.11.3 has an issue with es2015 bundle, and it has been fixed here #40456, and is available in 0.11.4. This issue will have some impact when user using the new bundle import 'zone.js' , So I think maybe we should use the new 0.11.4 version as the minimum support version?

[alan-agius4]

@JiaLiPassion, that would be possible, when is 0.11.4 scheduled to be released?

[JiaLiPassion]

@alan-agius4 , the release PR has been merged, I believe it will be released very soon.

[alan-agius4]

@JiaLiPassion & @gkalpak, I update the PR once zone.js 0.11.4 is released I'll update the PR with the new version.

@JiaLiPassion, can you please prioritize a zone.js release? Since this will also need to be synced in angular/angular-cli#20034

[JiaLiPassion]

@alan-agius4 , sure, I will contact @mhevery to make the new release.

[gkalpak]

Awesome work, @alan-agius4! Very thorough 💯

One last thing:
Should we update the reference to Angular CLI in packages/zone.js/README.md (line 32)?

-If you are using `Angular CLI`, the `polyfills.ts` file will contain:
+If you are using an older `Angular CLI`, the `polyfills.ts` file will contain:

(...or something along those lines.)

[alan-agius4]

Updated PR to use zone.js 0.11.4.
