tests : refactor test-recurrent-state-rollback (#29426)

• tests : use llama_context_ptr in test-recurrent-state-rollback

Replace raw llama_context pointers with llama_context_ptr and drop the
manual llama_free calls and cleanup lambda.

• tests : run test-recurrent-state-rollback over all dummy models

Add a --models DIR mode that mirrors test-save-load-state: iterate every
dummy model, report PASS/FAIL/SKIP in a table and fail only when a model
fails. Register a single ctest entry with ARGS --models instead of the four
per-model registrations.

• cont : fix typo

• metal : allow fusing 0-element nodes to keep graph packing shape-independent

The fusion packing in ggml_metal_fusion_max excluded 0-element tensors and
the topk_moe/moe_reduce checks rejected n_tokens == 0, so graphs decoding
batches with no outputs packed differently from the worst-case reserved
graph. The Metal optimizer then reordered the nodes differently and
ggml_gallocr_needs_realloc failed on the layout mismatch, forcing an
unexpected graph re-reserve (caught by GGML_SCHED_DEBUG_REALLOC).

Treat empty tensors like their non-empty counterparts: match them in the
pattern sequence and only reject genuinely malformed shapes. Fused kernels
dispatch zero threadgroups for empty graphs, which is a legal no-op.

• tests : run test_multi_seq_split_replay as a separate test

test_multi_seq_split_replay was invoked at the end of test_rollback,
so its result was folded into the rollback status and it only ran when
the rollback part passed.

Give it its own test_status return, run both tests independently over
both cache fills via a shared run_tests helper, and report them as
separate rollback / split replay columns in the --models table with
per-test summaries. The exit code fails when either test fails.

• tests : loosen the split replay nmse bound to 1e-4

test-generate-models seeds its weights from std::random_device, and some
generated lfm2 models drift up to ~1.7e-5 nmse on the split replay due to
rounding noise, tripping the previous 1e-5 bound. Raise the bound to 1e-4
so the random generations stop flaking.

• tests : reuse run_tests_for_model in single-model mode

The single-model path duplicated the model init and the non-recurrent
check from run_tests_for_model; route it through the shared helper
instead. Model load failures now return FAIL rather than SKIP so that
--model with a broken file still exits non-zero, and the helper loads
with model_only like the --models loop does since the tests create
their own contexts.
