Preserve array-based string.Format expression trees

Proprietary

Group originally expanded string.Format object values into an explicit array inside a proven expression-tree lambda before retargeting. Preserve the original params-array overload when .NET 9 span params would prevent compilation. Retain ordinary delegates, fixed/normal-array calls, named/generic arguments, comments and conditional snapshots.
