Ettore Di Giacinto d11a152ad3 fix(turboquant): drop obsolete legacy-spec shim after fork rebased
The TheTom/llama-cpp-turboquant fork (pin c9aa86a) rebased past the
upstream common_params_speculative refactor (ggml-org/llama.cpp
#22397/#22838/#22964), the model_tgt rename (#22838) and get_media_marker
(#21962). The old fork-compat shim forced now-wrong legacy code paths,
breaking the build with errors like 'struct common_params_speculative has
no member named mparams_dft / type' and 'server_context_impl has no member
named model'.

Remove the obsolete LOCALAI_LEGACY_LLAMA_CPP_SPEC branches from the shared
grpc-server.cpp (stock llama-cpp and the modern fork both take the modern
path now), and narrow the one remaining gap (the fork still lacks
common_params::checkpoint_min_step) to a dedicated
LOCALAI_TURBOQUANT_NO_CHECKPOINT_MIN_STEP guard injected by
patch-grpc-server.sh. The patch script now only adds the turbo2/3/4
KV-cache types and injects that one macro.

# Patch the shared backend/cpp/llama-cpp/grpc-server.cpp *copy* used by the
# turboquant build to account for the gaps between upstream and the fork:
#
# 1. Augment the kv_cache_types[] allow-list so `LoadModel` accepts the
# fork-specific `turbo2` / `turbo3` / `turbo4` cache types.
# 2. Define LOCALAI_TURBOQUANT_NO_CHECKPOINT_MIN_STEP at the top of the file
# so the grpc-server option parser skips the two references to
# common_params::checkpoint_min_step (the default and the option handler).
# That field does not exist in the fork yet; drop this once it does.
#
# The fork used to lag upstream on the whole common_params_speculative refactor
# (ggml-org/llama.cpp#22397/#22838/#22964), the model_tgt rename (#22838) and
# get_media_marker (#21962), which required a much larger compat shim here
# (flat-field sed renames + a coarse LOCALAI_LEGACY_LLAMA_CPP_SPEC define). The
# fork has since rebased past all of those, so the only remaining gap is
# checkpoint_min_step. If a future bump reintroduces a divergence, add a narrow
# guard in grpc-server.cpp keyed on a fork-specific macro and inject it here
# rather than resurrecting the coarse one.
#
# We patch the *copy* sitting in turboquant-<flavor>-build/, never the original
# under backend/cpp/llama-cpp/, so the stock llama-cpp build keeps compiling
# against vanilla upstream.
#
# Idempotent: skips each insertion if its marker is already present (so re-runs
# of the same build dir don't double-insert).
