texture_cache: Basic handling of partially resident images (#3066)

* texture_cache: Avoid gpu tracking assert on sparse image

At the moment just take the easy way of creating the entire image normally and uploading unmapped subresources are zero

* tile_manager: Downgrade assert to error

* fix macos
