PDAL processing algorithms (e.g. "Export to raster" or "Export to raster
(using triangulation") and pdal_wrench.exe don't work in latest QGIS LTR
3.40.13, QGIS 3.44.5 and QGIS 3.99.0-Master.

The issues occurs also directly executing pdal_wrench in the OSGeo4W
Shell:
{{{
pdal_wrench.exe to_raster
--input=C:/Users/Andrea/Downloads/2034000_7275500_LIDAR2021.copc.laz

The issue doesn't occur if pdal_wrench.exe, provided by the qgis-
ltr-3.40.13-1 package, is replaced with the one from the qgis-
ltr-3.40.12-1 package.
I suppose the issue may be due to the fact that while pdal_wrench.exe in
qgis-ltr-3.40.13-1 is built against gdal312, pdalcpp.dll (which
pdal_wrench.exe depends on) is still build against gdal311.
