This patch adds ResolveDeferredExpectationsNow() as a helper function of dawn_end2end_tests to let all the deferred expectations be resolved and cleared immediately to avoid consuming too much memory for all the deferred expectations before the exit of the test body. We use ResolveDeferredExpectationsNow() in the end2end test CopyFromNonZeroMipLevelWithTexelBlockSizeLessThan4Bytes because previously because this test will always consume too much memory to allocate vectors and the allocation of std:vector will sometimes fail on the bots.

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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
