gpu: Optimistically use persistent access for D3DImageBacking

Previously, a D3DImageBacking flagged for potential WebGPU usage
would not use persistent access, preventing Graphite from deferring
submissions. This resulted in lost performance even if WebGPU was
never actually used.

This change enables persistent access by default for all
D3DImageBackings. The access is only revoked if a non-Graphite
device attempts to use the backing.

This allows canvases to benefit from deferred submissions, improving
performance in scenarios where WebGPU usage is enabled but not actually
used.

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.
