Update race_windows_amd64.syso to latest tsan (V3) runtime.
This version of the runtime depends on libsynchronization.a, so to
use this syso, you need to also be using a sufficiently up to date
version of GCC (notably GCC 5.1, installed on the Go windows builders
right now, does not include this library).
Updates #48231.
Updates #35006.
Fixes #49761.
