Implement GPUQueueDescriptor, device/queue labels

Implements GPUQueueDescriptor as well as communicating label attribute
changes for GPUDevice/GPUQueue to Dawn. Labels from the descriptors are
not passed to Dawn at the time of requestDevice due to how the
descriptor is currently being passed, but is instead set using the
setLabel() method immediately after creation. This should generally not
be observable unless there are errors during device creation that would
have included the label.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
