core: add convert between meter/feet to plannerShared

qPrefDiveplanner contains settings for ascent and descent in a neutral format.
diveplanner desktop uses a macro UNIT_FACTOR to convert between UI values and
qPref values.

In order not to dublicate these calculation (in C++ and QML) a set of shared
functions are made. The functions are identical to the calculations in diveplanner
desktop.
