Synopsis
Add support for on-the-fly vertical transformations in ArcGIS Field Maps

Description of Enhancement
According to

https://doc.arcgis.com/en/field-maps/android/help/high-accuracy-data-collection.htm

"Field Maps records orthometric height based on the geoid model of your receiver." As such, if the geoid height reported by a GNSS receiver is in meters, the z-values of a feature layer will hold orthometric heights in units of meters regardless of the vertical coordinate system defined for the layer. In lieu of this, this enhancement requests support for "on-the-fly vertical transformations" in ArcGIS Field Map so that orthometric heights can be converted into the vertical units of the feature layer's vertical coordinate system.

Note: Due to BUG-000161562, a vertical transformation cannot be applied in the generation of the z-value field.
