Ryan Harrison 7fc0c0519a Revert "Vulkan: honor bufferImageGranularity the simplest way."
This reverts commit 48183b8f58.

Reason for revert: Part of Dawn->Chromium breakage

BUG=dawn:950

Original change's description:
> Vulkan: honor bufferImageGranularity the simplest way.
>
> Vulkan requires that linear and opaque resources be placed in different
> "pages" of bufferImageGranularity size, as some hardware uses the page
> table to contain some compression bits or other stuff. Make Dawn honor
> this limit by aligning all allocations to bufferImageGranularity. This
> is pretty bad and should be improved later.
>
> Also does some cleanups:
>  - Add kMappableBufferUsage to represent all mappable usages.
>  - Remove the proxy function for resource management from
>    vulkan::Device and call ResourceMemoryAllocator directly.
>  - Use an enum to make the difference between mappable, linear and
>    opaque resources.
>
> This issue was found while doing a change of the memory type selection
> in Vulkan, that started failing some unrelated tests on Nvidia. Without
> knowing the details of the HW or the driver it is really hard to write
> tests, except by copy-pasting a failing test. This is why there is no
> test added in this CL, and instead will rely on tests not failing with
> the follow-up CL.
>
> Bug: dawn:659

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
