    [NTOS:IO] Implement IoConnectInterruptEx for fully specified interrupt types (#5416)
    
    Implement IoConnectInterruptEx() for CONNECT_FULLY_SPECIFIED.
    This gives ability to load various modern drivers that use IoConnectInterruptEx.
    
    Various drivers work after this change, such as serial.sys MS sample driver when
compiled with the reactos tree and many more KMDF drivers from later Windows versions.
