well_edit_tools: make separate make_projection_xyz() function
well_edit_tools: make separate make_projection_xyz() function

Return previous make_projection() with old parameters set (working in
ZYX tops direction) to support old code.
make_projection_xyz() works in XYZ direction and returns indexes of
cells where wellbore intersects unrolled 2D mesh, thus, no need to pass
huge scalars array as a parameter. Indexes is much more convinient
for client code.
