Feature request: Coordinate widget

[lp-dj]

I miss a widget in QGIS/ QField to handle coordinates appropriately.

What I would like is if you could tap on a coordinate field in the attribute form and the coordinate stored here is then passed on to the operating system as a geo URI to be opened, in order to pass it on to a navigation app of choice, for example (similar to how it is done with photos and camera apps or image viewers).

Currently, navigating to a specific point involves many additional clicks to copy and paste the coordinate. Among other things, because attribute values can only be copied from Edit mode (#2270).

For data entry, such a widget should accept coordinates via tap on the map in addition to manual entry.
