[QGIS-Developer] QgsProcessing vector types combobox

May I support this request by Matteo?
When processing geometries, undesired multi-geometries are a frequent
outcome. It may even be useful to show the users that that the procedure
has a multi-geometry output. This usually means there are uplanned outcomes
and that the algorithm is not properly configured and/or is a wrong
solution for your problem.
Anyway, being able to precede a process with a multi-to-single algorithm
would be really convenient.
Thanks for pointing this out.
