[GDAL provider] in create(), use newly create dataset handle to instanciate the provider (fix #17103)
Previously we created an empty file, close it and re-opened it immediately in open mode.
However for GeoPackage, if you create for example a 1 band or 3 band dataset, upon reopening
you get a 4 band RGBA dataset, due to the fact that GeoPackage doesn't explicitly store the
number of bands. Thus the 4th band (alpha) was never written by the QgsRasterFileWriter logic.
