Fix return type of SetProcessDpiAwareness aka SetProcessDpiAwarenessInternal
This function (documented as SetProcessDpiAwareness but exported as
SetProcessDpiAwarenessInternal) has a return type of HRESULT but we
declared it as returning BOOL. This triggered the following /analyze
warning:
src\chrome\app\chrome_exe_main_win.cc(104) : warning C6216:
Compiler-inserted cast between semantically different integral
types: a Boolean type to HRESULT.
