Improving geodesic distance for 3D mesurement

[tdipisa]

Description

With #10000 the geodesic distance for 3D measurement has been included. There are a few necessary modifications needed to make that measurement type usable and less ambiguous.

1 - When you draw the first point its position is not fixed in the view and this make the measurement ambiguous: the first point should be anchored at the clicked point

2 - Currently the measurement is drawn for consistency on the ellipsoid at the absolute 0 and this make unclear the measurement position in many cases (specially if you are working at urban level).

measure_2.mp4

The position of the measurement should be preserved as drawn by the user but it should be clearly indicated somehow that it is referencing a distance calculated at the absolute 0 (maybe we can do this info in tooltip and use guide).

What kind of improvement you want to add? (check one with "x", remove the others)

• Minor changes to existing features
• Code style update (formatting, local variables)
• Refactoring (no functional changes, no api changes)
• Build related changes
• CI related changes

@MV88 the height of the geodetic measurement changes when you switch to area and angle measurement. (on DEV and QA)
