[utils] Fix missing defines in src/utils

These defines were set up in src/dawn/common so when the code moved to
src/utils, they became undefined (i.e. false) all the time.

This bug affected debug builds of the following things:
- From https://dawn-review.googlesource.com/c/dawn/+/312837
  - DAWN_ASSERT, DAWN_UNREACHABLE, DAWN_RELEASE_ASSUME
  - Logging and abort in fuzzers
- From https://dawn-review.googlesource.com/c/dawn/+/312976
  - TypedInteger

Found while working on nocompile tests (though only because I noticed
the wrong branch of my ifdef was the one being tested). Linked bug is to
make this less fragile.

(Note these broke after branch 7871 so no merge will be required.)

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.
