e2b53643 - [CodeGen] Move CodeGenPGO behind unique_ptr (NFC) (#142155)

[CodeGen] Move CodeGenPGO behind unique_ptr (NFC) (#142155) The InstrProf headers are very expensive. Avoid including them in all of CodeGen/ by moving the CodeGenPGO member behind a unqiue_ptr. This reduces clang build time by 0.8%.
