[gdal-dev] Building GDAL from VCPKG fails with FreeXL

[Kai Pastor, DG0YT]

- The freexl port builds in vcpkg CI, and there are no open issues for 
Windows.
- Either there are log files for the actual error, reported on the 
console, or it fails early for example because of mixing different 
msys2/cygwin runtimes.
- freexl is an optional feature of port gdal. If nothing asks for it, it 
is not enabled in port gdal.
- However, libspatialite is a default feature of port gdal, and freexl 
is a default feature of port libspatialite. ATM it is not possible to 
opt-out from libspatialite[freexl], but this will be fixed with port 
gdal 3.11.1.
- To opt-out from all default features of a port, you must declare this 
in the top-level manifest (manifest mode) or by using the pseudo feaure 
"core" (classic mode).  The reason why you can't do this now with 
libspatialite[core] is that gdal[libspatialite] implicitly depends on 
the default features of port libspatialite.
