Implement Convert trait to convert between CPU and GPU images (#3194)

Browse Source 
* Add upload texture trait

* Make convert trait use explicit converter

* Add gpu texture download implementation

* Add footprint to convert trait

* Cleanup texture upload / download

* Download wgpu textures aligned

* abstract texture download into converter helper

* rename module

not only doing uploads anymore
conversion looks like a ok name

* Remove into_iter call and intermediate vector allocation
