Tom Hvitved 42faabc552 C#: Rename and restructure control flow graph entities

Follow a naming structure similar to the data flow library:

- `ControlFlowNode` -> `ControlFlow::Node`.
- `CallableEntryNode` -> `ControlFlow::Nodes::EntryNode`.
- `CallableExitNode` -> `ControlFlow::Nodes::ExitNode`.
- `ControlFlowEdgeType` -> `ControlFlow::SuccessorType`.
- `ControlFlowEdgeSuccessor` -> `ControlFlow::SuccessorTypes::NormalSuccessor`.
- `ControlFlowEdgeConditional -> ControlFlow::SuccessorTypes::ConditionalSuccessor`.
- `ControlFlowEdgeBoolean` -> `ControlFlow::SuccessorTypes::BooleanSuccessor`.
- `ControlFlowEdgeNullness` -> `ControlFlow::SuccessorTypes::NullnessSuccessor`.
- `ControlFlowEdgeMatching` -> `ControlFlow::SuccessorTypes::MatchingSuccessor`.
- `ControlFlowEdgeEmptiness` -> `ControlFlow::SuccessorTypes::EmptinessSuccessor`.
- `ControlFlowEdgeReturn` -> `ControlFlow::SuccessorTypes::ReturnSuccessor`.
- `ControlFlowEdgeBreak` -> `ControlFlow::SuccessorTypes::BreakSuccessor`.
- `ControlFlowEdgeContinue` -> `ControlFlow::SuccessorTypes::ContinueSuccessor`.
- `ControlFlowEdgeGotoLabel` -> `ControlFlow::SuccessorTypes::GotoLabelSuccessor`.
- `ControlFlowEdgeGotoCase` -> `ControlFlow::SuccessorTypes::GotoCaseSuccessor`.
- `ControlFlowEdgeGotoDefault` -> `ControlFlow::SuccessorTypes::GotoDefaultSuccessor`.
- `ControlFlowEdgeException` -> `ControlFlow::SuccessorTypes::ExceptionSuccessor`
