FF147 WebGPU supported on all apple silicon

[hamishwillee]

FF147 supports WebGPU on on all macOS versions on apple silicon in https://bugzilla.mozilla.org/show_bug.cgi?id=1993341. Previously it was only supported on Tahoe - I can't find a bug for that, but this issue stated that it was added for Tahoe in 145. It isn't supported on Linux. It isn't supported on macOS on Intel.

I have updated the (partial) subfeatures in the 250+ places that support is recorded.

We discussed this in today's BCD meeting, and it's a bit tricky:

• The DOM interfaces seem to actually be available on all platforms, even if requestAdapter() will not return an adapter.
• The notes currently don't explain what "unsupported" means.
