Improvements to how and what is stored in the texture caches. (#3834) ...

* Improvements to how and what is stored in the texture caches.
Built upon the good work from https://github.com/pixijs/pixi.js/pull/3789
+ For Text, the base textures were in the BaseTextureCache, but textures weren't in the TextureCache. This has been fixed
+ Now able to tell the BaseTexture the origin of where the canvas being passed through has come from. ie. was it from the text class? was it from the graphic class? was it from caching as a bitmap? More information now to track where these canvases (canvii??) have been generated from
+ BaseTexture has addBaseTextureToCache and removeBaseTextureFromCache functions, to match regular Texture. Any adding or removing to the BaseTextureCache is now through these functions

! Breaking change. When you call Texture.fromTextureFromCache - it no longer automatically removes it's base texture from the base texture cache. Not sure how people feel about this

? I don't like lines 233 to 236 in Texture.js, and line 591 in BaseTexture.js - I don't see why they are there or why they are needed, but I chickened out on removing them!

* Renaming function to more generic names

* Adding deprecation layer

* Fixed trying to add texture to BaseTexture cache causing unit test fail

* Fixed reading from the wrong cache

* Able to remove textures and base textures from their caches via object instances
Added debug warning if trying to add a texture to a cache id that already exists
Added unit tests

* Default string for texture origin

* Different object creation style

* textureCacheId is now an array of potential entries

* textureCacheId changed to textureCacheIds

* Removed unneeded string creation

* Changes ticker priority with UPDATE_PRIORITY const

* Fixes linting

* Use a linked list approach to ticker listeners

* Oops fixes test

* Minor fixes

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

Dev texture update (#3820) ...

* lint. again.

* trailing spaces

* move TextureTransform back
