Reland "Vulkan: Allow setting multiple `MemoryKind` bits"

This is a reland of commit a8f733807cbf72ebab8baecbda359ca4413d00c7

This patch no longer requires the support of DEVICE_LOCAL_BIT for
the buffer memory created from a host mapped pointer.

Original change's description:
> Vulkan: Allow setting multiple `MemoryKind` bits
>
> This patch allows setting multiple MemoryKind bits in one MemoryKind
> value and replaces MemoryKind::Opaque with MemoryKind::DeviceLocal as
> a preparation of the implementation of BufferMapExtendedUsage on
> Vulkan.

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.
