Clarify some wgpuSurfaceConfigure() error behavior

[kainino0x]

• Handle the case where there's no device.
• Clarify what happens when the device is lost. (Lost devices don't report errors so we allow ImplementationDefinedLogging but otherwise squelch the errors. We also still validate that the device isn't lost, but this never results in a normative error because the error won't be reported.)
• Clarify that struct chaining errors also produce device errors.
