Hans Wennborg 2eed63bcfa Remove support for using link order files on Windows 
Since crrev.com/824529, we're using /call-graph-profile-sort instead,
which means the linker lays out the binary based on the PGO profile.

Updating the Windows .order files

Since #824529, order files are no longer used for linking Chromium on Windows. Instead, the linker orders the binary contents based on profile-guided optimization (PGO) data, using LLD's call graph profile sort feature. That provides similar benefits and uses use the existing PGO infrastructure instead of requiring maintenance of the order files. See crbug.com/1077279.
