Add more Qualcomm compute device ids

Only 8340 (0x37314430) and 8380 (0x363343xx) are derived from A7xx,
while all the earlier compute GPUs are based on A6xx.

A summarization of QC compute GPUs can be found at
https://docs.google.com/spreadsheets/d/1wybODaXljgkhsBKadHtOWsGpVbIk7vR48B9-Rqsn_JY/edit?gid=0#gid=0

Please note Qualcomm_ACPI is used for D3D12 (compute), while
Qualcomm_PCI (phone and compute) is used for Vulkan. In theory, all the
devices in Qualcomm_ACPI should also be part of Qualcomm_PCI as they may
run on Vulkan, and both masks should be 0xFFFFFF00. Currently I don't
have enough detailed info about phone, so this CL leaves out the changes
to Qualcomm_PCI.

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.
