CreateGeomField is not overwriten for FGdbLayer, so that Capability should be false on the datasource.

This was preventing the creation of FileGDB layers when the geometry field was required. It was being called here https://github.com/OSGeo/gdal/blob/trunk/gdal/apps/ogr2ogr_lib.cpp#L3683 because of this https://github.com/OSGeo/gdal/blob/trunk/gdal/apps/ogr2ogr_lib.cpp#L3529-L3530

 * accept tiles of small dimensions (github #210)

XYZ driver:

== OGR 2.2.0 - Overview of Changes ==

Core:
 * Layer algebra: Add KEEP_LOWER_DIMENSION_GEOMETRIES=YES/NO option to Intersection, Union and Identity.
Default is yes, but it is set to no unless result layer is of geom type unknown.
If set to no, result features which would have lower dim geoms are skipped
if operating on two layers with same geom dim.
 * Fix crash/corrupted values when running importFromWkb() on POLYGON M/POLYGON ZM geometries (#6562)
 * Add OGR_WKT_PRECISION config option that defaults to 15 to select the number of decimals when outputting to WKT
 * Make OGRFeature::SetField(string) accept JSon serialized arrays for the String/Integer/Integer64/RealList types; add reciprocal OGRFeature::GetFieldAsSerializedJSon() for those types
 * OGRGeometryFactory::transformWithOptions(): better deal with reprojection from polar projection to WGS84, and projections crossing the antimeridian to WGS84, by splitting geometries prior to reprojection (#6705)
 * LinearRing transformTo(): force last point to be identical to first one in case it is not.
 * GML geometry parsing: avoid 'Cannot add a compound curve inside a compound curve' error (#6777)
 * OGR SQL: fix IN filtering on MapInfo indexed columns (#6798)
 * OGR SQL: add support for LIMIT and OFFSET keywords
 * OGR SQL: add comparisons on date / datetime (#6810)
 * OGR SQL: increase efficiency of DISTINCT operator
 * OGREnvelope: change initialization to fix issue when getting MULTIPOINT(0 0,1 1) envelope (#6841)
 * OGRParse: fix parsing logic to avoid false positive detection of string as datetime (#6867)

OGRSpatialReference:
 * Upgrade to EPSG database v9.0 (#6772)
 * OGRCT: upgrade LIBNAME of mingw and cygwin to libproj-9.dll and cygproj-9.dll to be up-to-date with proj 4.9.X (recommended method is using ./configure --with-static-proj4 instead) (#6501)
 * importFromESRI(): fix import of multi line MERCATOR SRS (#6523)
 * morphToESRI(): correctly compute standard_parallel_1 of Mercator(2SP) projection from scale factor of Mercator(1SP) (#6456, #4861)
 * exportToProj4(): recognize explicit OSR_USE_ETMERC=NO to avoid using etmerc with proj >= 4.9.3
 * importFromProj4(): do not set a AUTHORITY node for strings like '+init=epsg:XXXX +some_param=val'
 * importFromProj4(): be robust with missing proj.4 epsg dictionary when importing '+init=epsg:xxxx +other_parm=value'
 * AutoIdentifyEPSG(): add identification of EPSG:3995 (Arctic Polar Stereographic on WGS84) and EPSG:3031 (Antarctic Polar Stereographic on WGS84)
 * OGRCoordinateTransformation: avoid potential bugs in proj.4 on NaN input
 * importFromEPSG(): take into account DX,DY,DZ,RX,RY,RZ,DS columns in pcs.csv to add per-PCS TOWGS84 overrides (geotiff #52)
 * Coordinate transformation: prevent unnecessary coordinate transformations (github #184, #185)

Utilities:
 * ogr2ogr: do not return error on ogr2ogr --utility_version
 * ogr2ogr: keep -append and -overwrite when -update follows
 * ogr2ogr: fix heuristics to detect likely abs…
