Change check to assert for VVL error

On WebView we are receiving VVL errors from the driver when Vulkan
object labels are disabled. This results in a DAWN_CHECK failing and
WebView crashing. It's not entirely clear why the driver is sending
messages with VK_DEBUG_UTILS_MESSAGE_TYPE_VALIDATION_BIT_EXT set, as VVL
should be disabled in release builds, but there is some discussion in
the bug.

Either way the error handler is just to alert developers that something
is wrong. Change it back to DAWN_ASSERT() to avoid crashing in release
builds.

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.
