This fixes the following build warnings in a mingw environment:

../../lldb/source/Host/windows/MainLoopWindows.cpp:226:50: warning:
format specifies type 'int' but the argument has type
'IOObject::WaitableHandle' (aka 'void *') [-Wformat]
226 | "File descriptor %d already monitored.", waitable_handle);
| ~~ ^~~~~~~~~~~~~~~
../../lldb/source/Host/windows/MainLoopWindows.cpp:239:49: warning:
format specifies type 'int' but the argument has type 'DWORD' (aka
'unsigned long') [-Wformat]
238 | error = Status::FromErrorStringWithFormat("Unsupported file type
%d",
| ~~
| %lu
      239 |                                                 file_type);
          |                                                 ^~~~~~~~~
