134c2019b1 gpu: remove Queue.WorkDownCallback lifetime footgun 
The previous implementation required the specific Queue struct that
submit() was called on to be valid when the callback is triggered. By
storing a pointer instead, the Queue does not need to be valid, only the
callback itself.

2b994d6b24 gpu: Fix build in 32-bit platforms 
Because of the use of u64, this currently fails to build in 32-bit
platforms like wasm. usize is platform dependent but safe enough for
most use cases.

c535e041bd gpu: correct default TextureView.Descriptor.format value 
According to kangz `WGPUTextureFormat_Undefined` is the correct default value for
`TextureView.Descriptor.format`. According to the spec, the default should be the
associated _Texture_'s descriptor.format, but it seems Dawn internally handles
this when set to `Undefined` - we will take the same approach.

gpu: fix alignment issues with getMappedRange, getConstMappedRange (#223) 
fixes alignment issues with getMappedRange, getConstMappedRange

Prior to this change `getMappedRange` and `getConstMappedRange` would not handle alignment to `COPY_BUFFER_ALIGNMENT` for users, and so invocation could result in an unhelpful error message:

```
    thread 254201 panic: attempt to use null value
    .../mach/gpu/src/NativeInstance.zig:1721:42: 0x480747
    in .gpu.NativeInstance.buffer_vtable.getMappedRange (game)
            return @ptrCast([*c]u8, range.?)[0..size];
					 ^
```

To address this:

1. Ensure we always request a 4-byte aligned buffer when `createBuffer` is called.
2. Ensure we always map 4-byte aligned buffers.

fbbb0b0ae0 gpu: use Dawn adapter creation API for now so that GPU_BACKEND selection works 
`webgpu.h` does not expose a method of choosing the GPU backend (vulkan, opengl, opengles, etc.)
at present. The only way to achieve this is to use Dawn's C++ API, which we expose as C shims
under the `machDawnNative*` prefix.

For now, we will use the Dawn adapter creation API so that we can choose between Vulkan/OpenGL/OpenGLES
etc via the `GPU_BACKEND` env var.

In the future, I believe we can do something nicer here. For example, perhaps we extend our `requestAdapter`
method (after all, we do not need to strictly match `webgpu.h`) to take such an option and be Dawn-aware so
that it handles this more seamlessly behind the scenes.
