Description of Change

Refs electron/build-images#55.

Fixes #48441.

This PR adds basic test coverage for Wayland, which is now the default display protocol in most major Linux distributions.

1. New test-wayland job: this job only runs on Linux x64 for now. It could also be set up as a variation of the existing test job, but I wanted to keep things separate at first. The job depends on the weston compositor to exist in the image: electron/build-images#55.
2. Chromium patch: the patch prevents the test script from crashing on teardown in the minimal Weston environment. (Chrome itself works around this with a custom build of Weston.) It is a simple safety check which will also be submitted upstream.
3. Wayland test spec allowlist: not all tests pass on Wayland, and many are not important since they do not care about the display server. I added api-app-spec.ts for now as it's a great indicator for "does the app launch"? The biggest win for regression testing will be the browser window spec, but that will take a decent amount of work.
4. isWayland helper: within allowed test specs, some will still need to be filtered out for compatibility. I added this to two tests in app.ts, one which is already skipped on CI anyway, and another which is probably a legitimate Wayland bug.

You can test on Linux by installing the deps (weston and wlheadless-run) and then running:

./script/actions/run-tests-wayland.sh e test --runners=main --files spec/api-app-spec.ts.
