TILING_SCHEME is a bit particular as a creation option in the GPKG driver. You 
can pass it with -co

In gdal_translate mode, it will automatically do the "right thing", that is 
reprojecting to the expected target CRS and picking up an appropriate zoom 
level.

In gdalwarp mode, you must help the driver a bit by also specifying the 
correct target SRS -t_srs EPSG:4326 , and you also must specify a target 
resolution with -tr that matches exactly one of the zoom levels of the tiling 
scheme. The COG driver has the needed magic for that but that involves making 
gdalwarp and the driver to be aware of each other, which hasn't been done for 
the GPKG driver.
