Replace hardcoded new_geom_type with user configuration

[spwoodcock]

• Let the user select which type of geometry type they want to draw (a draw toolbar), then allow them to submit for any type of drawn geometry?

• Rename or remove new_geom_type as it's a bit redundant in addition to point,polygon,linestring selection field

  • NOTE: instead decided to have primary_geom_type field

• During project creation data extract download, give the user checkboxes for point,polygon,linestring, for which type of geometries they wish to extract (e.g. it could be mixed point/polygon, or only polygon)

  • Replaced with Allow project creators to select specific feature types for OSM data download #2193

Requirements identified by @manjitapandey

• If user upload points as map features during project creation: visualise those points on project details page and mapper's page. Remaining workflow similar to those of polygons. - expected 👍
• If user uploads polygons only as map features : visualise those as polygons on project details page and mapper's page. -Current behavior is polygon is visualised as points on mapper's page - Not expected behavior
• If user uploads both point and polygon: Visualise them as they are uploaded.
