Rename QgsGeometry::fromPolyline as QgsGeometry::fromPolylineXY
...
and add new QgsGeometry::fromPolyline which uses QgsPoint
We want to encourage people not to use the QgsPointXY method, as it drops
Z/M values. So it's moved across to a different name to make way
for a new QgsGeometry::fromPolyline which uses a QgsPoint list
instead of QgsPointXY, thus keeping Z/M values intact.
Similarly, QgsPolyline now is a list of QgsPoint (keeping z/m values)
and the old 2d QgsPolyline type was renamed to QgsPolylineXY.
Making the QgsPoint method the "preferred" method and making linestrings
just as easy to create from z/m dimensioned points as 2d points is
important to push people to write code which does not discard
these important dimensions.
As a bonus, the QgsPoint methods are more efficient anyway, since
they don't require creation of a temporary list.
