feat(material/dialog): add the ability to control the animation duration

Since the dialog animation is on the `MatDialogContainer`, consumers aren't able to disable the animation. These changes add properties to the dialog config that allow consumers to set the duration of the dialog's enter and exit animations.

Fixes #3616.

+### Configuring dialog content via `entryComponents`
+
+Because `MatDialog` instantiates components at run-time, the Angular compiler needs extra
+information to create the necessary `ComponentFactory` for your dialog content component.
+
+For any component loaded into a dialog, you must include your component class in the list of
+`entryComponents` in your NgModule definition so that the Angular compiler knows to create
+the `ComponentFactory` for it.
+
+```ts
+@NgModule({
+  imports: [
+    // ...
+    MatDialogModule
+  ],
+
+  declarations: [
+    AppComponent,
+    ExampleDialogComponent
+  ],
+
+  entryComponents: [
+    ExampleDialogComponent
+  ],
+
+  providers: [],
+  bootstrap: [AppComponent]
+})
+export class AppModule {}
+```
+
+### Controlling the dialog animation
+You can control the duration of the dialog's enter and exit animations using the
+`enterAnimationDuration` and `exitAnimationDuration` options. If you want to disable the dialog's
+animation completely, you can do so by setting the properties to `0ms`.
+
+<!-- example(dialog-animations) -->
+
 ### Accessibility
 
 `MatDialog` creates modal dialogs that implements the ARIA `role="dialog"` pattern by default.
