Subject : Try again to flip official win builders to GN.
Author  : dpranke
Commit description:
  
We believe we've fixed the remaining known issues w/ the upload/
signing scripts, so it's time to try again. This affects:

- chromium.perf
  - Win Builder
- official.desktop
  - win
  - win64
- official.desktop.continuous
  - win beta
  - win stable
  - win trunk
  - win64 trunk

(Though the beta and stable builders aren't actually affected and
won't be until they are on M54).
