RISC-V: Remove 256/512/1024 VLS vectors
Since https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=2e7abd09621a4401d44f4513adf126bce4b4828b
we only allow VLSmodes with size <= TARGET_MIN_VLEN * TARGET_MAX_LMUL.
So when -march=rv64gcv default LMUL = 1, we don't have VLS modes of 256/512/1024 vectors.
Disable them in vect test which fixes the following FAILs in the regression:
FAIL: gcc.dg/vect/bb-slp-pr65935.c -flto -ffat-lto-objects scan-tree-dump-times slp1 "optimized: basic block" 11
FAIL: gcc.dg/vect/bb-slp-pr65935.c scan-tree-dump-times slp1 "optimized: basic block" 11
FAIL: gcc.dg/vect/bb-slp-subgroups-2.c -flto -ffat-lto-objects scan-tree-dump-times slp2 "optimized: basic block" 1
FAIL: gcc.dg/vect/bb-slp-subgroups-2.c scan-tree-dump-times slp2 "optimized: basic block" 1

* lib/target-supports.exp: Remove 256/512/1024 vectors.
