Message : Generators: Use fixed year in license headers. Remove dynamic year generation from generator scripts, as required by the Chromium C++ style guide. The dynamic year values were replaced by the current year at the time the file was created according to git log. The code to dynamically generate the year was removed. This patch also refreshes generated files and hashes. Bug: angleproject:5516 Change-Id: I735028bccb5c83217e92c380538f1abf0a906b2c Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2690950 Commit-Queue: Lubosz Sarnecki <lubosz.sarnecki@collabora.com> Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
