Improve texture caching by allowing weak refs and more formats (#4447)

Browse Source 
* Destroy GPU textures when the last reference drops

* Request pooled textures synchronously

* Pool cached textures by format

* Add the owned GPU buffer type

* Route the remaining GPU allocations through the executor

* Add weak texture parking to the texture cache

* Raise the texture cache budget to 1GB for native and 512MB for wasm
