Refactor classes in RigWellResultPoint.h

* Move RigWellResultFrame implementation into separate file
Update/correct includes accordingly

* First step of moving attributes from public to private
- Move public members to private and create interface
- Single public member remains due to strong dependency on usage of reference and reference to its object public members

* Second step of moving attributes from public to privatee
- Remove usage of reference directly to attributes. Interface with copy and set.
- Moving attributes in RigWellResultFrame and RigWellResultBranch

* Move class RigWellResultBranch into separate file
