384369c3c4 Rename QgsVectorLayerImport to QgsVectorLayerExporter 
Since the majority of users of this class will be exporting
an existing map layer to a data provider, the QgsVectorLayerImport
name is misleading and suggests that this class is designed
just to bring layers "into" QGIS.

Explicitly naming the class "Exporter" should help API users
discover this class.

Also cleanup API and improve docs

f84d703234 Add method QgsProcessingUtils::mapLayerFromString 
Algorithms and other processing code should use this method
(instead of dataobjects.getLayerFromString) to
retrieve layers from a string, as it considers the processing
context and allows resolving strings to temporarily stored layers.

This permits processing models to function correctly when
intermediate results are stored as memory layers. Subsequent
model algorithms can then access these temporary layers as inputs.
All temporary layers will be removed when the context object
is destroyed after the model algorithm is run.

Do not pass in getConsoleCommand just to get commandName for shortHelp.
This avoid errors with non initialized parameters.

f247a7cda3 Add c++ optimised uniqueValues method which respects processing context 
Remove processing vector.uniqueValues/vector.getUniqueValues
and port usage to c++ method

Should be much faster than the python method, as the c++ method takes
advantage of handing off the unique values calculation to the
provider source whenever possible
