Encoder can't create less constrained DCI than current encoding

Description

DCI has the scope of the whole bitstream. The VTM encoder sets many of the constraint flags as tight as possible, i.e. whenever a tool is disabled the according constraint set flag is automatically set.

This way it is not possible to create a stream containing DCI, which is expected to be spliced with another stream that has different coding tools enabled.

Each flag should have a config file option, which could be configured as follows:

ToolConstraintFlag = 0 # disabled
ToolConstraintFlag = 1 # enabled
ToolConstraintFlag = 2 # automatically set (default)
