Previously, Converter::convertMeasure parsed measure strings and
performed unit conversion in a single call. This was appropriate, as all
such measure strings could be converted to a common unit ahead of time.
tdf#36709, however, will introduce measures that are relative to the
current font and font size. In order to perform layout, the original
measure unit must be preserved and passed along with the original value.
This change introduces Converter::convertMeasureUnit, which parses a
measure string and returns both the value and the unit. Existing unit
conversion code has been refactored to facilitate this change.
