Small tweaks to Condition derivation code

• ConditionAccessHolder: use std::queue instead of std::list (as std::queue has by default the same element validity guarantees as std::list on push and pop -- iterator invalidation doesn't matter here -- and offers the minimal interface required)
• ConditionDerivation: take a span instead of a vector as c'tor argument
• IConditionDerivationMgr: use span instead of vector, add forwarding function which takes a single element
• ConditionUpdateContext: add const to map value -- updaters should not be allowed to change the ParamValidObject which they are provided with!
• adapt code to the above, and avoid copying VP sensors in a loop...
