Debugger[New CDB]: Work on QList.

Move container size code to container.cpp/h and known type
enumeration to separate knowntype.h.
Add some more types. Change type detection to work without
'class '/'struct ' prefixes for inner types. Add Qt types with
Movable/Primitive flags. Add QStack/QQueue, size for std::deque
and std::stack. Add infrastructure for linked-list type containers
and std::list. Implement QList specialisations depending on type.
