fd2c18ee16 Refactor processing writer to use QgsFeatureSink, and to store
temporary output layers in the provided processing context

Should fix loss of intermediate memory layers when running
a multi-step model

377b181c4e Port more processing dataobjects methods to c++
Also
- simplify and add tests
- remove large memory leak (persistant store of all non-project layers)
- remove broken support for direct loading postgres/virtual layers
by string (Python version was very broken and would never match
a postgres/virtual layer)

a0bd464232 Use formatted name for algorithm names
Avoids conversion of names later and gives clearer separation
between visible names and internal names

ede452be85 [processing] Port feedback object to c++
Algorithms are now passed a QgsProcessingFeedback object
instead of the loosely defined progress parameter.

1e661e37b9 [FEATURE][processing] New 'drop geometries' algorithm
Simply removes any geometries from an input layer and returns
the features with attributes only
