Add uncapturedErrorCallbackInfo to requestDevice descriptor

[beaufortfrancois]

This PR adds uncapturedErrorCallbackInfo to requestDevice() descriptor to match recent Dawn changes at https://dawn-review.googlesource.com/c/dawn/+/183162.

It also removes wgpuDeviceSetUncapturedErrorCallback that will be deprecated with this new attribute.

Let me know if that looks good to you.

(Please also cc @lokokung about changes to sync these headers, since he's usually the one who has implemented them in Dawn.)

@kainino0x Thanks for the review! I've addressed your feedback and will keep @lokokung updated about upcoming changes.

Note that I'll open a separate PR for WGPUDeviceLostCallbackInfo

[beaufortfrancois]

WGPUDeviceLostCallbackInfo currently contains WGPUCallbackMode mode which is not yet defined in webgpu.h. I guess this means we need to wait a bit more before adding it to webgpu.h when WGPUFuture are actually defined. What do you think?

Oh yes, fair point. I forgot DeviceLost is promise-based and UncapturedError is not. Makes sense to separate them then.

I am not sure how soon we'll be ready to roll in the promise changes, but I think we're very close. Maybe when we do that we should deal with the generator thing first before rolling all that in, but TBD.
