[M140] [dawn][native][d3d12] Force higher minimums for maxDynamic* limits

Adding maxImmediateSize to D3D12 took space away from
maxDynamicUniformBuffersPerPipelineLayout and
maxDynamicStorageBuffersPerPipelineLayout, which is a regression.
Set those first, so that allocating maxImmediateSize can't take away
from them.

This should be safe for all machines because kMaxRootSignatureSize and
the default values for the limits are all constants, so all this
allocation logic has the same logic on all machines.

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.
