Updates to TypeScript 4.3.4 which contains a fix for a printer
PR Close#42600
Switches the repository to TypeScript 4.3 and the latest
version of tslib. This involves updating the peer dependency
ranges on `typescript` for the compiler CLI and for the Bazel
package. Tests for new TypeScript features have been added to
ensure compatibility with Angular's ngtsc compiler.

Add back the zone.js externs file test for google closure compiler.
The test compiles a test program with and without `zone_externs`.
1. With `zone_externs`, the code should keep the APIs defined in the `zone_externs`.
2. Without `zone_externs`, the code will not keep these APIs.

Close#38851, support `jest` fakeTimers APIs' integration with `fakeAsync()`.
After enable this feature, calling `jest.useFakeTimers()` will make all test
run into `fakeAsync()` automatically.
```
beforeEach(() => {
jest.useFakeTimers('modern');
});
afterEach(() => {
jest.useRealTimers();
});
test('should run into fakeAsync() automatically', () => {
const fakeAsyncZoneSpec = Zone.current.get('FakeAsyncTestZoneSpec');
expect(fakeAsyncZoneSpec).toBeTruthy();
});
```
Also there are mappings between `jest` and `zone` APIs.
- `jest.runAllTicks()` will call `flushMicrotasks()`.
- `jest.runAllTimers()` will call `flush()`.
- `jest.advanceTimersByTime()` will call `tick()`
- `jest.runOnlyPendingTimers()` will call `flushOnlyPendingTimers()`
- `jest.advanceTimersToNextTimer()` will call `tickToNext()`
- `jest.clearAllTimers()` will call `removeAllTimers()`
- `jest.getTimerCount()` will call `getTimerCount()`
