This should probably just be objbase.h and winerror.h

On the other hand, I think we also need to add back SkLeanWindows.h to get
windows.h. We're currently getting it accidentally through OAIdl.h through a
chin of includes starting with ole2.h. (There's magic with COM_NO_WINDOWS_H, but
let's not go there.)

Done.

 #include "SkAutoCoInitialize.h"
 
 SkAutoCoInitialize::SkAutoCoInitialize() :
     fHR(
         CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE)
     )
 { }
 
 SkAutoCoInitialize::~SkAutoCoInitialize() {
     if (SUCCEEDED(this->fHR)) {
         CoUninitialize();
     }
 }
 
 bool SkAutoCoInitialize::succeeded() {
     return SUCCEEDED(this->fHR) || RPC_E_CHANGED_MODE == this->fHR;
 }
