Support that cache Sprite as Bitmap directly. (#3855) ...

* Cache Sprite as Bitmap directly.

In the current pixi.js , when we want to cache a sprite as Bitmap, we have to put the sprite add to a container , like this : 
```
var texture = PIXI.Texture.from(img);
var container = new PIXI.Container();
var sprite = new PIXI.Sprite(texture);
sprite.cacheAsBitmap = true;
container.addChild(sprite);
var renderTexture = PIXI.RenderTexture.create(sprite.width, sprite.height);
renderer.render(container, renderTexture);
```

With this PR , use could cache the sprite directly : 
```
var texture = PIXI.Texture.from(img);
var sprite = new PIXI.Sprite(texture);
sprite.cacheAsBitmap = true;
var renderTexture = PIXI.RenderTexture.create(sprite.width, sprite.height);
renderer.render(sprite, renderTexture);
```

* Update cacheAsBitmap.js

Prepare plugin support for objects with multiple BaseTextures (#3830) ...

* Add ability for Prepare plugin to upload the all textures for AnimatedSprites

* Add a new function to loop through all the textures of an AnimatedSprite and add them to the queue
* Moved Duplicate `findBaseTextures` function from WebGL & Canvas Prepare to Base prepare as static
* Moved all the `findObjectType` methods to their appropiate class as static methods for consistency

* Updated Comments to reflect "static" not "private" methods

* Added the findTexturesForAnimatedSprites logic to the standard findBasicTextures

This cleans up the need to worry about ordering the registration of hooks and only calls upload once

* Split the prepare.register function into 2 registerFindHook & registerUploadHook

* Some simple cleanup before the PR

* removed dependenvy on `extras` from prepare

* Fix small comment issues with pull request

Removed the [optional] reference in the comments for both
new register methods.
Added a small example to the docs

Lint wouldn't pass without the params in the JSDoc

* added `instanceof` check and fixed up the return true only if a texture is found
