Rework ZramMeter and remove MeterClass.comprisedValues
The 'comprisedValues' boolean property unnecessarily complicates the
drawing algorithms of Bar meters and Graph meters. Since the only user
of 'comprisedValues' is ZramMeter, it is better to rework the meter so
that it no longer needs 'comprisedValues'.
The 'values[ZRAM_METER_UNCOMPRESSED]' now stores the difference between
uncompressed and compressed data size.
