Bug 1644897 [wpt PR 24100] - Reland "Remove Document::IsFeatureEnable…

…d, use the ExecutionContext variants instead.", a=testonly

Automatic update from web-platform-tests
Reland "Remove Document::IsFeatureEnabled, use the ExecutionContext variants instead."

Was reverted because of callsites where GetDocument() was guaranteed
non-null, but GetExecutionContext() might be null if the Document is
detached. Fixed and added regression tests for the places where we got
crash reports.
