We should only generate the `providedIn` property in injectable
defs if it has a non-null value. `null` does not communicate
any information to the runtime that isn't communicated already
by the absence of the property.
This should give us some modest code size savings.
PR Close#34116
For injectables, we currently generate a factory function in the
injectable def (prov) that delegates to the factory function in
the factory def (fac). It looks something like this:
```
factory: function(t) { return Svc.fac(t); }
```
The extra wrapper function is unnecessary since the args for
the factory functions are the same. This commit changes the
compiler to generate this instead:
```
factory: Svc.fac
```
Because we are generating less code for each injectable, we
should see some modest code size savings. AIO's main bundle
is about 1 KB smaller.

Previously, the Angular AOT compiler would always add a
`ɵprov` to injectables. But in ngcc this resulted in duplicate `ɵprov`
properties since published libraries already have this property.
Now in ngtsc, trying to add a duplicate `ɵprov` property is an error,
while in ngcc the additional property is silently not added.

The size diff threshold of 1% has proven to be too lenient for us
to catch size regressions in AIO. Since the AIO main bundle is
between 400-500 KB, a size regression must be between 4-5 KB before
it will cause the tests to fail. As a result, we may merge many
changes with smaller regressions of a few KB before the size test
eventually lets us know that the number has increased. The hope is
that lowering the threshold will help us catch the smaller
regressions during code review and prevent the size tests failing at
a random later time when someone catches the size "hot potato".

This commit transforms the setClassMetadata calls generated by ngtsc from:
```typescript
/*@__PURE__*/ setClassMetadata(...);
```
to:
```typescript
/*@__PURE__*/ (function() {
setClassMetadata(...);
})();
```
Without the IIFE, terser won't remove these function calls because the
function calls have arguments that themselves are function calls or other
impure expressions. In order to make the whole block be DCE-ed by terser,
we wrap it into IIFE and mark the IIFE as pure.
It should be noted that this change doesn't have any impact on CLI* with
build-optimizer, which removes the whole setClassMetadata block within
the webpack loader, so terser or webpack itself don't get to see it at
all. This is done to prevent cross-chunk retention issues caused by
webpack's internal module registry.
* actually we do expect a short-term size regression while
https://github.com/angular/angular-cli/pull/16228
is merged and released in the next rc of the CLI. But long term this
change does nothing to CLI + build-optimizer configuration and is done
primarly to correct the seemingly correct but non-function PURE annotation
that builds not using build-optimizer could rely on.

The payload size increase in the ES5 bundles is (at least partially)
expected, due to fixing some down-leveling corner cases.

Upgrading to @angular/material 9.0.0-next.0 increases the bundle size
slightly (~1.3KB). This is a natural expectation of library
fixes/improvements.

The angular.io project uses Angular and CLI v9, which by default turns
on Ivy mode. However, since ec4381dd4, we explicitly opt out of Ivy.
This commit removes the `enabledIvy: false` configuration, thus allowing
the default behavior of having Ivy on.
NOTE:
This commit only changes the angular.io projects. The docs examples need
to be updated separately (first to Angular and CLI v9 and then to Ivy).

This patch is a final major refactor in styling Angular.
This PR includes three main fixes:
All temporary state taht is persisted between template style/class application
and style/class application in host bindings is now removed.
Removes the styling() and stylingApply() instructions.
Introduces a "direct apply" mode that is used apply prop-based
style/class in the event that there are no map-based bindings as
well as property collisions.

Bundle size changed in both zone.js(legacy) and zone-evergreen.js
- zone.js(legacy) package increased a little because the following feature and fixes.
1. #31699, handle MSPointer events PR
2. https://github.com/angular/zone.js/pull/1219 to add __zone_symbol__ customization support
- zone-evergreen.js package decreased because
1. the MSPointer PR only for legacy
2. the Object.defineProperty patch is moved to legacy #31660
