vect: Fix mask handling for SLP gathers [PR103761]
check_load_store_for_partial_vectors predates the support for SLP
gathers and so had a hard-coded assumption that gathers/scatters
(and load/stores lanes) would be non-SLP operations. This patch
passes down the slp_node so that the routine can work out how
many vectors are needed in both the SLP and non-SLP cases.

* tree-vect-stmts.cc (check_load_store_for_partial_vectors): Replace
the ncopies parameter with an slp_node parameter. Calculate the
number of vectors based on it and vectype. Rename lambda to
group_memory_nvectors.
(vectorizable_store, vectorizable_load): Update calls accordingly.
