Description
steps to replicate (is just an example):
- load a dem layer
- open the r.watershed tool, no input is filled, not the mandatory nor the optional > correct
- run the tool, it will create a number of outputs, close the tool
- re-open the tool, now all the inputs fields, mandatory and optional are already filled with one of the layers in the project > not cool, especially for the optional ones. But to keep consistency (also with 2.18) no input should be filed.

[processing] Fix optional layer parameters are filled by default
Refs #17471
Not a full fix for 17471 - that requires handling of optional
numeric values too
[processing] Fix optional numeric parameters cannot be cleared
Without this change optional numeric parameters have no way to
be cleared in the GUI - they are always forced to have a value
Fixes #17471 - but I've noticed that many optional numeric
GRASS parameters have a non-null default value. These may
need to be investigated and manually changed to None defaults
in the description files.
