fix(promise): can set native promise after loading zone.js

[JiaLiPassion]

fix #898, #891, #783

currently after loading zone.js, if we load some libraries which will override global Promise, Zone.assertZonePatched will throw error, and angular will not started.
Sometimes we use 3rd party libraries and hard to control the load orders. So we need a better way to handle this process.

in this PR.

1. patch global.Promise with a setter by using Object.defineProperty , so after loading zone.js, if a new Promise want to override global.Promise, it will not update the global.Promise, but update the underlying NativePromise, so the whole process will be:

   • before loading zone.js, NativePromise is Browser built in Promise.
   • load zone.js, global.Promise is ZoneAwarePromise, global[symbolPromise] is NativePromise.
   • after loading zone.js, set other Promise, such as es6-promise, global.Promise is still ZoneAwarePromise, and global[symbolPromise] will be updated to es6-promise.

2. Zone.assertZonePatched will only throw error when user set this before loading zone.js

__Zone_disable_Promise = true;

This looks like a good idea. Let me know when it is ready.

@mhevery , I have resolved the conflict and rebased, please review.

And I also disable safari 9.3 jasmine test on ios 9, because in saucelabs + jasmine, recently it is very slow on ios9 and will timeout on several cases, but in mocha it is ok, so ios9 will still be tested. And I will continue to tuning the ios9 jasmine cases.

This is great and will alleviate a huge pain for us. We have to load a variety of widgets from CDN built by different teams that all serve all sorts of Promise polyfills. Thank you for the fix! Looking forward to the next release of zone.js with this fixed

Looks like the error has returned, I can't execute my angular universal server-side app, node throws me that error when I try it.
This error has been fixed in multiple times and always return, looks like a nightmare!
