Option to Disable Dawn Logging

[jcalabro]

Hey there! Is there any way to disable logging from Dawn, perhaps by passing this ifdef? I did a bit of digging and I see that there is a LoggingType enum defined, but it doesn't appear to be used anywhere.

I'd like to be able to have stdout/stderr have no information for this particular project as we have our own logging system.

$ zig build run
Warning: DiscoverDefaultPhysicalDevices is deprecated. Call EnumerateAdapters or RequestAdapter instead.

Thanks!

Hi! Using DAWN_DISABLE_LOGGING is the way to do it I think. This isn't to exposed to the build system right now because we use prebuilt Dawn lib. I will have a think about how to resolve this issue.

We should also fix cause of the warning #468
