Add LIBERTIFF driver: native thread-safe read-only GeoTIFF reader

This driver is based on the libertiff library for IFD and tag parsing.
It uses in a very controlled (and isolated) way internal libtiff LZW,
PackBits and LERC codecs (even if using external libtiff for the GTiff
driver). For Deflate/GZip, LZMA, ZSTD, it defers to GDAL
cpl_compressor.h API. For JPEG, WEBP, JPEGXL, it uses the corresponding
GDAL drivers to open strip/tile blobs as temporary datasets.

Note that at current time the driver isn't necessarily optimized to
minimize the number of network requests for COG layout.

The driver supports most TIFF formulations, but not necessarily the most
exotic ones that the GTiff libtiff based might support. In particular it
does not support non-power-of-two BitsPerSample value (could be added
with extra coding). On the plus side, JPEGXL is supported as soon as the
JPEGXL driver is available at runtime (contrary to the GTiff driver which requires
using internal libtiff since the tif_jxl.c codec hasn't been upstreamed
to libtiff yet).

As noted in the documentation, no side-car file at all are currently
used by this driver.
