Revert "EGL: Move initialization of EGL inside a DisplayEGL class"

This reverts commit 9fba7ea8e943cb9396c356c4becb6842ef0710d5.

Reason for revert: causes WebGL2 CTS failures when rolling into Chromium

Original change's description:
> EGL: Move initialization of EGL inside a DisplayEGL class
>
> The moves initialization and checks of EGLDisplays to be in its own
> class instead of split across opengl::Backend and
> opengl::PhysicalDevice. That class also contains data that's per EGL
> connection such as the EGLDisplay and the procs. This removes the need
> for opengl::Backend to return a single PhysicalDevice ever.
>
> The ContextEGL class now only deals with creating context and doing
> MakeCurrent, with some of its validation checks moved to classes using
> it. This will make it easier to dynamically handle EGL extension being
> present (e.g. to support webgpu.h when EGL_KHR_image_base is not present).
>
> Finally the encapsulation in these classes is step towards supporting
> more embedder APIs in the future (like GLX).

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.
