[webkit-dev] WPT tests and runtime-enabled features

Hi Ali,

Yes this is something we should have a solution for. Right now, we have two
- Enabling the runtime-enabled flag only in DumpRenderTree/WebKitTestRunner
- Updating WebKit testharnessreport.js to call internal APIs for some/all
WPT tests

Ideally, we should be able to set additional configuration information to
WPT tests without modifying them.
A configuration file alongside the WPT test might be feasible and could
supersede the <!--- webkit-test-runner [enableFeatureName=true] -->
Folder-based hierarchical configuration might be nice but I am unsure
whether that would meet the complexity tradeoff bar.
Nothing yet started there so any help would be greatly appreciated!
