Migrate DQTDataFlowMonTool to use ReadHandle.

Note the objects produced by MuonCreatorAlg as transient in objKeyStore.
Needed for the output streams to get the correct dependencies in MT.

In C++11, implicit declarations of copy and assignment are deprecated if the
class has a user defined destructor or copy or assignment.  gcc9 now warns
about this by default.
Adjust to avoid the warning.

Some methods of Tile containers,
which allow modifying the contents of containers,
violate the const correctness.

Clients of these methods are migrated to use Tile mutable containers,
which allow modifying the contents of containers in controlled manner.

So, TileRawCorrelatedNoise algorithm have been migrated to use
Tile mutable digits container.
