isolated-context-stable

This suite runs wpt_internal/isolated-permissions-policy/ tests with --isolated-context-origins=https://web-platform.test. It's an analog of the isolated-context virtual test suite which, compared to that suite, is the same except this isolated-context-stable suite runs with stable flags.

As of 2024-08-29, there's one test in this suite:

• wpt_internal/permissions-policy/: Verify that the IWA-specific APIs are included in the permissions policy results. These APIs should only be available in an isolated context which this test runs under. See //third_party/blink/web_tests/VirtualTestSuites for where that's configured.
