Subject: [PATCH] grass.pygrass: Mark test_raster_region resampling tests xfail
 on Windows

Follow-up to #7902: fixing the resource leak there turned a fatal,
whole-file-crashing FERROR into three individually diagnosable
failures instead. The remaining issue is real but distinct from the
leak: the small region these tests set up isn't actually restricting
what RasterRow reads back (rast[0] comes back with roughly 100000
elements instead of 10).

Built GRASS locally and confirmed this is genuinely Windows-specific,
not a state leak reproducible here: the file passes reliably on Linux
both run in isolation and as part of the full 359-file gunittest suite
in sequence. Marking xfail on Windows per the existing convention
rather than guessing at a fix that can't be verified; needs
investigation with actual Windows access.
