Prevent explicit creation of textures with multiplanar formats

Some backend APIs don't let you create multiplanar textures directly.
Because we don't need this right now, disallow it. The multiplanar
formats feature is restricted to just wrapping external textures now.
A separate feature can be added in the future for explicit creation.

- moves existing validation tests to end2end tests since we need a
  backend to wrap yuv textures
- hardens validation such that uninitialized multiplanar textures
  cannot be wrapped. This is because they are currently only valid
  for readonly usages - meaning Dawn is unable to perform the
  initialization.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
