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.

a127378b19 gpu-dawn: update Dawn to latest revision as of 2022-04-18 
Effectively a redo of hexops/mach#231 where I messed up the submodule update by accident.

Updates Dawn to latest revision as of 2022-04-18 c7b7b6def6

* Followed https://github.com/hexops/dawn/tree/main/mach#updating
* The UB issue should now actually get fixed (once CI builds the binary releases.)
* Verified example runs on macOS.

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.
