win: Enable WinSboxNoFakeGdiInit for Debug component builds (see #3708)

The WinSboxNoFakeGdiInit feature requires delayload of all DLLs that
might load user32.dll in the renderer process. It's enabled as a field
trial for all non-Official builds, but caused problems with Debug
component builds using VS 17.5.0 due to MSVCP140D.dll depending on
OLE32.DLL (which depends on user32.dll). The dependency on OLE32.DLL
is removed with VS 17.9.2 so the feature can now be enabled.

See https://crbug.com/326277735#comment39 for background.
