Reviewed by Brady Eidson.

Do more raw value validation when constructing an ObjectIdentifier. In
particular, we now extend the validation to forbid HashTable deleted
values (not just empty ones).

* Source/WTF/wtf/ObjectIdentifier.h:
(WTF::ObjectIdentifierGenericBase<uint64_t>::isValidIdentifier):
(WTF::ObjectIdentifierGenericBase<uint64_t>::hashTableDeletedValue):
(WTF::ObjectIdentifierGenericBase<UUID>::isValidIdentifier):
(WTF::ObjectIdentifierGeneric::ObjectIdentifierGeneric):
* Source/WTF/wtf/UUID.h:
(WTF::UUID::isHashTableDeletedValue const):
(WTF::UUID::operator bool const):
* Source/WebCore/loader/DocumentThreadableLoader.cpp:
(WebCore::DocumentThreadableLoader::loadRequest):
