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

* Removes EventEmitter dependency from ticker

* Small optimization to avoid Function.call

* Changes ticker priority with UPDATE_PRIORITY const

* Fixes linting

* Use a linked list approach to ticker listeners

* Oops fixes test

* Minor fixes

Fixed graphics

Big refactor

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

More updates added the mini-runner

Dev texture update (#3820) ...

* use texture transforms

* Plane accounted for texture transform before, now we can remove it

* move TextureTransform to the core
"uploadUvTransform" setting

* some user shaders have no uTransform

* fix canvas

* better docs

* bucking lint

* lint. again.

* trailing spaces

* move TextureTransform back

TilingSprite matrix calculation fix (#3831)

Control whether use core.ticker.shared to update (#3429) ...

* Control whether use core.ticker.shared to update

Add a argument to control whether use core.ticker.shared to update animation.

Related Issue :  https://github.com/pixijs/pixi.js/issues/3428

Default value is true.
```
new AnimatedSprite(textures)  ---> use core.ticker.shared to update, as same as current version.

new AnimatedSprite(textures, false)   ---> don't use core.ticker.shared to update.
```

* Update JSDoc &  Change autoUpdate to selfUpdate .

* Change selfUpdate back to autoUpdate

This is the last time I modified this PR.
Because I decide to write a new one.

If you don't want to merge this PR ， you could close it anytime.

* add    @private to autoUpdate

* Update AnimatedSprite.js

* this.autoUpdate --> this._autoUpdate

Improved documentation ...

Class member documentation improved via removal of unnecessary @memberofs - more members now show up in the docs.
Class getter/setter documentation improved using technique above, and also by removing documentation for setters. Documentation was only showing the setter docs, whereas the getter is where the important information is. JSDoc maintainers themselves recommend just doccing the getter jsdoc3/jsdoc#973
Documented a few classes to let devs know that they are automatically created by PIXI and added to renderer.plugins, like interactionManager and prepare

^ This PR is wrong, it takes into the accountonly one of the two situations. 

After changing from worldTransform to localTransform, caching is proper for all cases.
