patch 8.2.4837: modifiers not simplified when timed out

    patch 8.2.4837: modifiers not simplified when timed out

    Problem:    Modifiers not simplified when timed out or using feedkeys() with
                'n" flag.
    Solution:   Adjust how mapped flag and timeout are used. (closes #10305)
