Reland "Enable D3D12 render pass and use PRESERVE usage on null RTV slots"

This is a reland of commit 6c2fd524f18e175bc502402f7f2c9e9cf351fd5c

In this patch we only enable the check on D3D12_FEATURE_DATA_D3D12_OPTIONS18
with D3D12 SDK version 612 (Windows SDK version 26100) to unblock the
roll of Dawn into Skia.

Original change's description:
> Enable D3D12 render pass and use PRESERVE usage on null RTV slots
>
> This patch enables the use of D3D12 render pass by checking
> `D3D12_FEATURE_DATA_D3D12_OPTIONS18.RenderPassesValid` and uses
> `PRESERVE` usage instead of `NO_ACCESS` on null RTV slots because
> using `NO_ACCESS` means the null RTV will not be bound for raster
> and consume the slots, thus the non-null RTVs will be bound to
> wrong slots.

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.
