2ab4c288 - [clang-repl] Delegate CodeGen related operations for PTU to IncrementalParser (#137458)

[clang-repl] Delegate CodeGen related operations for PTU to IncrementalParser (#137458) Read discussion : https://github.com/llvm/llvm-project/pull/136404#discussion_r2059149768 and the following comments for context Motivation 1) `IncrementalAction` is designed to keep Frontend statealive across inputs. As per the docstring: “IncrementalAction ensures it keeps its underlying action's objects alive as long as the IncrementalParser needs them.” 2) To align responsibilities with that contract, the parser layer (host: `IncrementalParser`, device: `IncrementalCUDADeviceParser`) should manage PTU registration and module generation, while the interpreter orchestrates at a higher level. What this PR does 1) Moves CodeGen surfaces behind IncrementalAction: GenModule(), getCodeGen(), and the cached “first CodeGen module” now live in IncrementalAction. 2) Moves PTU ownership to the parser layer: Adds IncrementalParser::RegisterPTU(…) (and device counterpart) 3) Add device-side registration in IncrementalCUDADeviceParser. 4) Remove Interpreter::{getCodeGen, GenModule, RegisterPTU}.
