CSE candidates had separate storage for the first candidate and subsequent candidates. This introduces some awkwardness when adding the second candidate to the list. Refactor things so that the first candidate is stored inline in `CSEDsc` as a normal list entry.

Pull Request Overview
Refactor the storage of CSE candidates by replacing separate fields for the first occurrence (csdTree, csdStmt, csdBlock) with an inline tree statement list (csdTreeList).
- Replace pointer fields with a value struct for the tree statement list in CSEdsc.
- Update all references and iterations from direct csdTree access to csdTreeList.tslTree accordingly.
