Target: 42-x-y
Manual backport of #51815 to 42-x-y.
- Wires 42-x-y release builds to consume the Electron-generated PGO profiles collected on this branch (run 26778371370: 8/8 platforms + V8 builtins, Chromium 148)
- State files point at the
02044ed2bc-stamped profiles uploaded from that run - Identical mechanics to main: state files + gclient download hooks + a Chromium patch that resolves profiles through the standard
chrome_pgo_phase = 2machinery
Notes: Improved runtime performance.
