Include ThreadGroup from WebBackForwardList

Reviewed by Richard Robinson.
We want to apply SWIFT_SHARED_REFERENCE to the WTF ref counted base class
types, so that all ref counted WebKit classes are treated as foreign
reference-counted types from Swift. This causes the Swift clang importer to
consider far more types than it previously did, and some small changes are
required to keep it happy.
This particular change is needed because WebBackForwardList transitively
includes a Ref<ThreadGroup>, via around nine layers of nested types. Swift
believes that it needs to be able to retain and release the ThreadGroup field,
and thus it needs visibility into the whole ThreadGroup type from within the
clang module which contains WebBackForwardList.
This is deemed to be kind-of a Swift bug in that it's being a bit
overenthusiastic trying to import the ThreadGroup type just because we have a
Ref<ThreadGroup> data field, but for now, this is necessary.
