[dawn] Fix clang warnings

On clang-14 and earlier, there's a whole bunch of warnings, like:

```
dawn/src/dawn/native/CommandAllocator.h:260:5: warning: unknown attribute 'always_inline' ignored [-Wunknown-attributes]
    DAWN_FORCE_INLINE uint8_t* AllocateData(size_t commandSize, size_t commandAlignment) {
    ^~~~~~~~~~~~~~~~~
dawn/src/dawn/common/Compiler.h:129:29: note: expanded from macro 'DAWN_FORCE_INLINE'
                            ^~~~~~~~~~~~~~~~~~~~
```

Add `DAWN_HAS_CPP_ATTRIBUTE()` macro that wraps `__has_cpp_attribute()`,
and use this to detect support for `clang::always_inline`.

Change the GCC path's `__always_inline__` attribute to `always_inline`,
as this is what we check for, and is the far more common way of
specifying this.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
