zone.js provides a flag DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION to let zone.js
throw the original error instead of wrap it when uncaught promise rejection found.
But the rejection value could be anything includes primitive value such as number.
In that case, we should not attach any additional properties to the value.

in the XMLHttpRequest patch, when get `readystatechange` event, zone.js try to
invoke `load` event listener first, then call `invokeTask` to finish the
`XMLHttpRequest::send` macroTask, but if the request failed because the
server can not be reached, the `load` event listener will not be invoked,
so the `invokeTask` of the `XMLHttpRequest::send` will not be triggered either,
so we will have a non finished macroTask there which will make the Zone
not stable, also memory leak.
So in this PR, if the `XMLHttpRequest.status = 0` when we get the `readystatechange`
event, that means something wents wrong before we reached the server, we need to
invoke the task to finish the macroTask.

zone.js 0.11.1 introduces a breaking change to adpat Angular package format,
and it breaks the module loading order, before 0.11, in IE11, the `zone.js` es5
format bundle will be imported, but after 0.11, the `fesm2015` format bundle will
be imported, which causes error.
And since the only purpose of the `dist` folder of zone.js bundles is to keep backward
compatibility, in the original commit, I use package redirect to implement that, but
it is not fully backward compatible, we should keep the same dist structure as `0.10.3`.
PR Close#38797
Before Zone.js `v0.11.1`, Zone.js provides two format of bundles under `dist` folder,
`ES5` bundle `zone.js` and `ES2015` bundle `zone-evergreen.js`, these bundles are used
for `differential loading` of Angular. By default, the following code
```
import 'zone.js';
```
loads the `ES5` bundle `zone.js`.
From `v0.11.1`, Zone.js follows the [Angular Package Format]
(https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs),
so the folder structure of the Zone.js bundles is updated to match `Angular Package Format`.
So the same code
```
import 'zone.js';
```
loads the `ES2015` bundle.
This is a breaking change, so if the apps import zone.js in this way,
the apps will not work in legacy browsers such as `IE11`.
Zone.js still provides the same bundles under `dist` folder to keep backward
compatibility after `v0.11.1`. So the following code in `polyfills.ts` generated
by `Angular CLI` still works.
```
import 'zone.js/dist/zone';
```

zone.js monkey patches the `Object.defineProperty` API long time ago
angular/zone.js@383b479
to resolve issues in very old version of Chrome web which override the
property of `CustomElements`, and this is not an issue any longer, so
we want to remove this monkey patch, since it may swallow the errors when the user
want to define property on unconfigurable or frozen object properties.
But currently there are several apps and tests depends on this patch, since
it also change the `configurable` property to `true` by default, so
in this PR we update the logic to not to swallow error any longer unless the property
is the callbacks of `document.registerElements`.
BREAKING CHANGE:
ZoneJS no longer swallows errors produced by `Object.defineProperty` calls.
Prior to this change, ZoneJS monkey patched `Object.defineProperty` and if there is an error
(such as the property is not configurable or not writable) the patched logic swallowed it
and only console.log was produced. This behavior used to hide real errors,
so the logic is now updated to trigger original errors (if any). One exception
where the patch remains in place is `document.registerElement`
(to allow smooth transition for code/polyfills that rely on old behavior in legacy browsers).
If your code relies on the old behavior (where errors were not thrown before),
you may need to update the logic to handle the errors that are no longer masked by ZoneJS patch.

//spyObj will have someFunction, but will not have aProperty
let spyObj = TestBed.get(SomeService);

Because `jasmine.createSpyObj` will create the `aProperty` with `enumerable=false`,

In the early Zone.js versions (< 0.10.3), `ZoneAwarePromise` did not support `Symbol.species`,
so when user used a 3rd party `Promise` such as `es6-promise`, and try to load the promise library after import of `zone.js`, the loading promise library will overwrite the patched `Promise` from `zone.js` and will break `Promise` semantics with respect to `zone.js`.
Starting with `zone.js` 0.10.3, `Symbol.species` is supported therefore this will not longer be an issue. (https://github.com//pull/34533)
Before 0.10.3, the logic in zone.js tried to handle the case in the wrong way. It did so by overriding the descriptor of `global.Promise`, to allow the 3rd party libraries to override native `Promise` instead of `ZoneAwarePromise`. This is not the correct solution, and since the `Promise.species` is now supported, the 3rd party solution of overriding `global.Promise` is no longer needed.
PR removes the wrong work around logic. (This will improve the bundle size.)

In the current version of zone.js, zone.js uses it's own package format, and it is not following the rule
of Angualr package format(APF), so it is not easily to be consumed by Angular CLI or other bundle tools.
For example, zone.js npm package has two bundles,
1. zone.js/dist/zone.js, this is a `es5` bundle.
2. zone.js/dist/zone-evergreen.js, this is a `es2015` bundle.
And Angular CLI has to add some hard-coding code to handle this case, o5376a8b139/packages/schematics/angular/application/files/src/polyfills.ts.template (L55-L58)
This PR upgrade zone.js npm package format to follow APF rule, https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs/edit#heading=h.k0mh3o8u5hx
The updated points are:
1. in package.json, update all bundle related properties
```
"main": "./bundles/zone.umd.js",
"module": "./fesm2015/zone.js",
"es2015": "./fesm2015/zone.js",
"fesm2015": "./fesm2015/zone.js",
```
2. re-organize dist folder, for example for `zone.js` bundle, now we have
```
dist/
bundles/
zone.js // this is the es5 bundle
fesm2015/
zone.js // this is the es2015 bundle (in the old version is `zone-evergreen.js`)
```
3. have several sub-packages.
1. `zone-testing`, provide zone-testing bundles include zone.js and testing libraries
2. `zone-node`, provide zone.js implemention for NodeJS
3. `zone-mix`, provide zone.js patches for both Browser and NodeJS
All those sub-packages will have their own `package.json` and the bundle will reference `bundles(es5)` and `fesm2015(es2015)`.
4. keep backward compatibility, still keep the `zone.js/dist` folder, and all bundles will be redirected to `zone.js/bundles` or `zone.js/fesm2015` folders.

`zone.js` supports jest `test.each()` methods, but it
introduces a bug, which is the `done()` function will not be handled correctly.
```
it('should work with done', done => {
// done will be undefined.
});
```
The reason is the logic of monkey patching `test` method is different from `jasmine` patch
// jasmine patch
```
return testBody.length === 0
? () => testProxyZone.run(testBody, null)
: done => testProxyZone.run(testBody, null, [done]);
```
// jest patch
```
return function(...args) {
return testProxyZone.run(testBody, null, args);
};
```
the purpose of this change is to handle the following cases.
```
test.each([1, 2])('test.each', (arg1, arg2) => {
expect(arg1).toBe(1);
expect(arg2).toBe(2);
});
```
so in jest, it is a little complex, because the `testBody`'s parameter may be bigger than 1, so the
logic in `jasmine`
```
return testBody.length === 0
? () => testProxyZone.run(testBody, null)
: done => testProxyZone.run(testBody, null, [done]);
```
will not work for `test.each` in jest.
So in this PR, I created a dynamic `Function` to return the correct length of paramters (which is required by jest core), to handle
1. normal `test` with or without `done`.
2. each with parameters with or without done.

By default, `zone.js` wrap uncaught promise error and wrap it to a new Error object with some
additional information includes the value of the error and the stack trace.
Consider the following example:
```
Zone.current
.fork({
name: 'promise-error',
onHandleError: (delegate: ZoneDelegate, current: Zone, target: Zone, error: any): boolean => {
console.log('caught an error', error);
delegate.handleError(target, error);
return false;
}
}).run(() => {
const originalError = new Error('testError');
Promise.reject(originalError);
});
```
The `promise-error` zone catches a wrapped `Error` object whose `rejection` property equals
to the original error, and the message will be `Uncaught (in promise): testError....`,
You can disable this wrapping behavior by defining a global configuraiton
`__zone_symbol__DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION = true;` before importing `zone.js`.

Currently we only run Saucelabs on PRs using the legacy View Engine
build. Switching that build to Ivy is not trivial and there are various
options:
1. Updating the R3 switches to use POST_R3 by default. At first glance,
this doesn't look easy because the current ngtsc switch logic seems to
be unidirectional (only PRE_R3 to POST_R3).
2. Updating the legacy setup to run with Ivy. This sounds like the easiest
solution at first.. but it turns out to be way more complicated. Packages
would need to be built with ngtsc using legacy tools (i.e. first building
the compiler-cli; and then building packages) and View Engine only tests
would need to be determined and filtered out. Basically it will result in
re-auditing all test targets. This is contradictory to the fact that we have
this information in Bazel already.
3. Creating a new job that runs tests on Saucelabs with Bazel. We specify
fine-grained test targets that should run. This would be a good start
(e.g. acceptance tests) and also would mean that we do not continue maintaining
the legacy setup..
This commit implements the third option as it allows us to move forward
with the general Bazel migration. We don't want to spend too much time
on our legacy setup since it will be removed anyway in the future.
