Change the default value of `dom.webgpu.enabled` from `false` to `true` in Nightly builds.
Everything in `dom/webidl/WebGPU.webidl` that is `Exposed=(Window)` is also gated on the `dom.webgpu.enabled` pref, so it should not appear on `window` in beta or release builds.
Beyond that, WebGPU is not usable in beta or release builds regardless of the pref setting, because of these lines of code in `dom/webgpu/Instance.cpp`:
#ifdef RELEASE_OR_BETA
if (true) {
return "WebGPU is not yet available in Release or Beta builds.";
}
#endif
This function is the only way to create a `GPUAdapter`, which is the only way to access any interesting parts of the WebGPU API.
The mochitest `dom/webgpu/mochitest/test_disabled.html` checks that the value of the `dom.webgpu.enabled` pref is `false`. This is now only appropriate in beta and release builds, so change `dom/webgpu/mochitest/mochitest-no-pref.ini` accordingly.
Update feature gate description in `toolkit/components/featuregates/FeatureGate.toml`.
