WebGPU: fail request for adapter when not available.

[gterzian]

Depends on #30888

See the changes at https://github.com/servo/servo/pull/30888/files/4bec9ef169f51c91f616b854e231484bbd983366#diff-95aa2eb890fe794918afdadfb6a89e026ec80222ceb8e5a21768d528e9ce036cR2066

This will simply leave the async handler in script waiting forever, instead we should send a message back and properly handle the case where WebGPU is not available(re "properly", look at the spec .

See

servo/components/script/dom/gpu.rs

Line 108 in 8bbcf0a

let sender = response_async(&promise, self);

@gterzian @lucasMontenegro can I pick this one?

[lucasMontenegro]

Hello @gterzian and @Taym95. I'm sorry I somehow missed this thread. Thanks to your comment it finally came to my attention @Taym95 .

I'm unable to contribute now since I just installed a new OS that I'm unfamiliar with. Maybe tomorrow I'll be ready to contribute again. I'm okay with someone else taking over, of course.

[gterzian]

Ok, there is no rush. @lucasMontenegro please let us know if you prefer that @Taym95 takes it...

[lucasMontenegro]

Yeah, I'm okay with it
