docs(llama.cpp): note tensor split now works with quantized KV cache (#10135)

The split_mode: tensor description claimed tensor parallelism requires
KV-cache quantization to be disabled. ggml-org/llama.cpp#23792 lifts that
restriction by extending the meta backend to preserve shape information
through KV-cache flatten/reshape, so cache_type_k/cache_type_v
quantization can be combined with -sm tensor on builds that include it.

Documentation only: no backend code, grpc-server.cpp comment, or
llama.cpp pin changes.

Default: `true`. Auto-disabled by the server if `kv_unified=false` or `cache_ram=0`. | `cache_idle_slots:false` |
 | `n_ctx_checkpoints` or `ctx_checkpoints` | integer | Maximum number of context checkpoints per slot (used for partial-prefix recovery, e.g. SWA). Default: `32`. | `ctx_checkpoints:16` |
 | `checkpoint_min_step` or `checkpoint_min_spacing` (aliases: `checkpoint_every_nt`, `checkpoint_every_n_tokens`) | integer | Minimum spacing in tokens between context checkpoints. `0` disables the minimum-spacing gate. Default: `256`. (Renamed upstream from `checkpoint_every_nt`; semantics shifted from a fixed cadence to a minimum spacing.) | `checkpoint_min_step:1024` |
