[wpt] Disable swiftshader for `*headless_shell_wpt_tests`

https://crrev.com/c/5955968 enabled swiftshader to fix some minor `css/`
rendering regressions, but ended up increasing total test runtime by as
much as 50%, as well as regressing tests in other areas
(`html/canvas/`). Disable swiftshader by default for now, and move any
"fixed" (now broken again) `css/` tests back to content shell. To be
migrated, those `css/` tests may need to run in an exclusive virtual
suite that enables swiftshader.

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.
