geography/gdal*: Update to 3.4.1

Packaging changes:

  Drop patch to visibility define code in port/cpl_conv, because gdal
  builds on NetSBD 9 without it, it had a merge conflict, it is not
  explained in a comment or commit message, and it hasn't been filed
  upstream.

Upstream changes (see NEWS.md for more detail):

* [RFC 81](https://gdal.org/development/rfc/rfc81_coordinate_epoch.html):
  Support for coordinate epochs in geospatial formats.
  Implemented in FlatGeoBuf, GeoPackage, MEM, VRT
* New GDAL drivers:
  - [Zarr](https://gdal.org/drivers/raster/zarr.html):
    read/write support for ZarrV2 (and experimental V3), using 2D classic raster
    API or multidimensional API:
  - [STACIT](https://gdal.org/drivers/raster/stacit.html):
    Spatio-Temporal Asset Catalog Items as virtual mosaics
* Other improvements:
  - number of enhancements in file system operations of /vsigs/
  - NITF: additions to comply with NITF Version 2.1 Commercial Dataset
    Requirements Document (NCDRD)
  - ODBC and PGeo: multiple fixes and improvements

    subdataset naming)
  - multidimensional API: caching, and other improvements
