Add Z/M support to Processing - WAS: "Extract nodes" drops m values

Processing needs to be updated to support z and m geometry values supported by QGIS core.

For example, result of the "Extract nodes" are just simply XY points.

In contrast the nodes_to_points(geometry, ignore_closing_nodes) function available in expressions does honor m and z values.

Currently Processing does not adopted to support Z/M/ZM values, so all similar algs are affected.

Extract nodes is fixed in 1b1dc7d

I think specific reports should be open for other algorithms. Many which rely on GEOS and other libraries will be upstream issues, but there's also other QGIS native ones which we can fix.
