54ec5acf1f [processing] GDAL algorithms can now be canceled! 
Previously there was no way to terminate the GDAL process, so if you
accidently got some parameter values wrong it was very easy to end
up with a quasi-endless, non-cancelable gdal algorithm burning away cpu in the
background of a qgis session... ouch!

50b5e563af [processing] Use QgsBlockingProcess instead of subprocess to run GDAL algorithms 
This gives us much more flexibility when running the process, as we can
now do things like report feedback messages directly without having
to resort to potentially unsafe event loops regardless of whether the
algorithm is run in the main or a background thread.

fe58d4956c [processing] don't set any default value for optional NODATA parameter 
in GDAL rastrize algorithm (fix #39752).

As this is optional parameter better to have it not set by default to
avoid unexpected conversion of valid values to nodata values.

b89d7fd088 [processing][gdal] Don't default to placing each input file in a separate 
band in build vrt algorithm

Creating a multi-band vrt is much less common vs creating a mosaic
style vrt, so set the default to the most common use case
and most predictable outcome.

6c44073ff0 [Processing] Fix GDAL Assign Projection: update QgsRasterLayer crs 
Even if the projection is assign, the QgsRasterLayer and the QgsRasterDataProvider was not updated.

The fix reloads the QgsRasterDataProvider's data and updates the QgsRasterLayer's crs.

40db7f9efd [processing] Fix subset string is ignored for vector layers when 
running GDAL algorithms

If a subset string is set, we must export the subset of the layer
for use by the GDAL command*

Fixes #35981

* well, we probably **should** just build the gdal command to include
the SQL definition of the subset filter, but that's non-trivial, so
this fix is a good simple solution for now

5b6589f6dc Cleanup QgsCoordinateReferenceSystem WKT enum 
- alias WKT_2018* to new WKT_2019* values, since the spec is actually
2019, not 2018
- add WKT_PREFERRED value which currently aliases to WKT2_2019, but
can be changed if/when future bumps to the WKT spec happen
- add WKT_PREFERRED_GDAL which should be used whenever a CRS is
exported to WKT for use with GDAL API. Aliases to WKT2_2019 currently,
but can be changed if/when a new spec is released and GDAL supports it
