Define MeterModeId to unsigned int and use it throughout

All uses of meter drawing "mode" numbers now have the type
`MeterModeId`, including the uses in structures and arrays.
`MeterModeId` is defined as `unsigned int`, as (currently) it doesn't
save any code size by defining it to any smaller type.
