docs : refresh CPU ops support matrix (#29666)

The committed docs/ops/CPU.csv is out of sync with the current
test-backend-ops suite: 11 ops with CPU support (COL2IM_1D,
MUL_MAT_HADAMARD, SWIGLU_CLAMP, MUL_MAT_W4A4/W4A8, MUL_MAT_ID_W4A4/W4A8,
DSV4_HC_COMB/PRE/POST, LIGHTNING_INDEXER) are missing entirely, and
many other ops have fewer test cases than the suite generates now.
docs/ops.md (which CI requires to match the CSVs) therefore
understates CPU support.

Regenerated with:
  test-backend-ops support -b CPU --output csv > docs/ops/CPU.csv
  scripts/create_ops_docs.py

Note: ADD1 now reads unsupported on CPU because ggml_add1 is
GGML_DEPRECATED and the suite no longer generates test cases for it;
the CPU implementation itself is still present.
