Jelle Raaijmakers bf77aeb3dc Tests/LibWeb: Support WPT variant meta tags in test-web
Add support for WPT test variants, which allow a single test file to be
run multiple times with different URL query parameters. Tests declare
variants using `<meta name="variant" content="?param=value">` tags.

When test-web encounters a test with variants, it expands that test into
multiple runs, each with its own expectation file using the naming
convention `testname@variant.txt` (e.g., `test@run_type=uri.txt`).

Implementation details:
- WebContent observes variant meta tags and communicates them to the
  test runner via a new `did_receive_test_variant_metadata` IPC call
- test-web dynamically expands tests with variants during execution,
  waking idle views after each test completion to pick up new work
- Use index-based test tracking to avoid dangling references when the
  test vector grows during variant expansion
- Introduce TestRunContext to group test run state, and store a static
  pointer to it for signal handler access

This enables proper testing of WPT tests that use variants, such as the
html5lib parsing tests (which test uri, write, and write_single modes)
and the editing/bold tests (which split across multiple ranges).
