1135: Make all textures support usage COPY_SRC and COPY_DST r=kvark a=fintelia

**Description**
In WebGPU, all textures should be allowed to have usages COPY_SRC and COPY_DST. However, right now when Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES is enabled any features that the backend says can't be blitted to/from will not gain these capabilities. In particular, compressed textures may not support blitting while still allowing access via copies to/from buffers.
You can also see the defaults used when TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES is not requested:
8c00cbcc8e/wgpu-types/src/lib.rs (L1224-L1342)
**Testing**
I ran a [patched version of the wgpu-rs cube example](https://github.com/fintelia/wgpu-rs/tree/cube-bc4/examples/cube).

This is an active GitHub mirror of the WebGPU implementation in Rust, which now lives in "gfx/wgpu" of Mozilla-central. Issues and pull requests are accepted, but some bidirectional synchronization may be involved.
WebGPU
This is the core logic of an experimental WebGPU implementation. It's written in Rust and is based on gfx-hal with help of gpu-alloc and gpu-descriptor. See the upstream WebGPU specification (work in progress).
The implementation consists of the following parts:
- internal Rust API for WebGPU implementations to use
- Rust types shared between wgpu-core,wgpu-native, andwgpu-rsplayer- standalone application for replaying the API traces, useswinit
This repository contains the core of wgpu, and is not usable directly by applications.
If you are looking for the user-facing Rust API, you need wgpu-rs.
If you are looking for the native implementation or bindings to the API in other languages, you need wgpu-native.
