POC Additional parameter mapping

Description

Working POC for additional parameters mapping.

• Supports additonal parameter for A -> B mappings
• Maps to properties only (no constroctor mapping rn)
• Only passes parameters down when needed, even if the method is recursive or doesn't directly use the parameter
• Support IReferenceHandler, this loigic could be used on to only pass IReferenceHandler to methods that use it

Changes:

• NewInstanceObjectMemberMappingBodyBuilder checks for matching additional parameters after trying the source value.
• IMapping has a Parameters property
• MappingBuilder checks for if a mapping is being built (prevents infinite loop), adding it to MappingCollection.Incomplete
  • MappingBodyBuilder.BuildBody this way NewInstanceObjectMemberMappingBodyBuilder is called early to see which parameters are used in its property mappings
  • MappingBuilderContext tracks which parameters have been used when creating a building the mapping. These are used by MappingBuilder to update which parameters were used for a given mapping.
  • Mappings which don't use extra paramerers are added to MappingCollection._mappings otherwise they are added to MappingCollection._scopedMappings
• MappingCollection._scopedMappings are limited for use by the UserDefinedMapping that created it. This prevents resolving/config issues.

Fixes #103
