Allow peeking at the gpu::Mailbox used by a GPUTexture.

`endWebGPUAccess` will need to retrieve the gpu::Mailbox from an
existing GPUTexture. This should always be possible because we
control `beginWebGPUAccess`, and its textures are created in a
predictable way (via a shared image). The prerequisite accessors
are added in this CL. Also, GPUTextures now hold on to the
gpu::Mailbox name post-construction, so it can be retrieved later.
These are small (16 bytes?) so should be a negligible cost.

`endWebGPUAccess` now invokes the accessors and checks that they
returned reasonable values. In a followup, the mailbox will be used
to replace the canvas' image.

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.
