b637c7fe22 Prevent background execution of zonal stats 
This algorithm is NEVER safe to run in the background, because
it directly modifies a layer in place.

We should:
- make a variant of this algorithm which returns a new layer
AND
- refactor the QgsZonalStats code to create a separate map
of feature->stats, and then modify the existing Zonal Stats
algorithm to apply these changes in a post processing step

6a2625664e [processing] Add dedicated "distance" parameter 
This is a subclass of QgsProcessingParameterNumber, but specifically
for numeric parameters which represent distances. It is linked
to a parent parameter, from which the distance unit will
be determined, and is shown using a dedicated distance widget
within the processing parameters panel. This widget shows
the distance unit.

This avoids the confusion when running algorithms which
use distances where the unit depends on a layer or CRS parameter -
e.g. the distance parameter in the buffer algorithm gives
the distance in layer units... so now we can show those units
directly within the dialog. Hopefully this leads to less
user confusion and accidental "1000 degree buffers"!

Additionally - if the unit is in degrees, a small warning
icon is shown next to the parameter. The tooltip for this
icon advises users to reproject data into a suitable
projected local coordinate system.

Initially implemented for the native buffer and single
sided buffer algorithm only - but more will be added.

Fixes #16290
