fuse: Check for large folio with SPLICE_F_MOVE

fuse: Check for large folio with SPLICE_F_MOVE

xfstest generic/074 and generic/075 complain result in kernel
warning messages / page dumps.
This is easily reproducible (on 6.19) with
CONFIG_TRANSPARENT_HUGEPAGE_SHMEM_HUGE_ALWAYS=y
CONFIG_TRANSPARENT_HUGEPAGE_TMPFS_HUGE_ALWAYS=y

This just adds a test for large folios fuse_try_move_folio
with the same page copy fallback, but to avoid the warnings
from fuse_check_folio().
