Dimensions: report the measurement as soon as one is created (#2421) (#2438)

Browse Source 
* Dimensions: fill in the measurement when one is created (#2421)

A dimension made in the session kept measurement 0.0 until it was saved and reopened.
add_dim now sets it with the geometry call the DXF/DWG writer uses for group 42.
Block names are still assigned at save time. Test: a_new_dimension_reports_its_measurement.

* Parity checklist: regenerated after merging main

* Dimensions: a jogged radius dimension stores its radius as the measurement (#2421)

draw_jogged_radius set the text but not DimGeometry.measurement, so DIMJOGGED dimensions
kept measurement 0 (and the DXF/DWG group 42 was 0). It now sets the radius.
Test: jogged_radius asserts the stored measurement.

* Parity checklist: regenerated after merging main

* Dimensions: fill in a new dimension's text position when it is created (#2421)

A dimension made in the session kept text_mid (0,0) until it was saved and reopened.
add_dim now sets it from the same dimension_geometry result as the measurement, the
position the writer puts in group 11, unless the user placed the text.
Test: a_new_dimension_reports_its_text_position.
