TestComponentBuilder now lives in core/testing. compiler/testing contains a private
OverridingTestComponentBuilder implementation which handles the private behavior
we need to override templates. This is part of the effort to simplify the testing
imports and hide compiler APIs.
Closes#9585
BREAKING CHANGE:
`TestComponentBuilder` is now imported from `@angular/core/testing`. Imports
from `@angular/compiler/testing` are deprecated.
Before:
```
import {TestComponentBuilder, TestComponentRenderer, ComponentFixtureAutoDetect} from '@angular/compiler/testing';
```
After:
```
import {TestComponentBuilder, TestComponentRenderer, ComponentFixtureAutoDetect} from '@angular/core/testing';
```
Previously these symbols were exposed via platform-browser-dynamic, then we merged then into platform-browser
thinking that tools would know how to shake off the compiler and other dynamic bits not used with the offline
compilation flow. This turned out to be wrong as both webpack and rollup don't have good enough tree-shaking
capabilities to do this today. We think that in the future we'll be able to merge these two entry points into
one, but we need to give tooling some time before we can do it. In the meantime the reintroduction of the -dynamic
package point allows us to separate the compiler dependencies from the rest of the framework.
This change undoes the previous breaking change that removed the platform-browser-dynamic package.
