WebGPU - Support should be partial when shipped only on some OS

[stof]

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

Chrome has shipped WebGPU support on most Windows, macOS and Android since quite some time, but support is still missing on Linux (only available behind a flag).

Firefox 141 has shipped WebGPU support on Windows only (already marked as partial implementation).

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet)

What did you expect to see?

Support should be marked as partial when WebGPU is shipped only on a subset of the platforms on which the browser is shipped.

Did you test this? If so, how?

Loading https://webgpu.github.io/webgpu-samples/?sample=helloTriangle (or other samples) in Chromium on Linux

https://web-platform-dx.github.io/web-features-explorer/features/webgpu/ says that Baseline availability is blocked by Firefox, but it should be blocked by both Firefox and Chrome IMO.

Note that BCD has a note about the limited OS support, but still treats it as a full implementation.

Just to confirm - WebGPU is currently shipping:

• In Chrome* except on Linux
• In Firefox* only on Windows
• In Safari 26

* On devices with driver support - not older Android, lots of VMs, etc. (Safari always has driver support because it ships with the OS.)
