Support T2B copy for RGB9E5Ufloat on OpenGL/ES

Add RGB9E5Ufloat support in BlitTextureToBuffer. Using compute
shader to sample from the texture, pack the float values and
write the bytes to the buffer.

There are values that have multiple possible encodings. The
dawn_end2end_tests cannot resolve this case so the CopyTests_T2B
is skipped for this format on OpenGL/ES. We will rely on the CTS
coverage on this format.

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.
