Reland "Add GN args for using orderfile for Chrome OS"

This is a reland of 1189f5932fc0f2e67d332a98d9dc83b7c5172508

This fixes the problems on official Windows, and also moves
the LLD assertion into if-statement, so that for the cases that
don't want to use the orderfile, LLD guarantee is not needed.

Bug: chromium:950627, chromium:982179
Test: Chrome OS, Android are tested locally. Official windows is tested on Linux.
