Subject: [PATCH] llama: fix GGML_METAL=ON build - missing ggml-metal.h include
 in llama-dflash.cpp (#2134)

llama-dflash.cpp calls ggml_backend_is_metal() and
ggml_backend_metal_set_n_cb() inside an #ifdef GGML_USE_METAL block but
never includes ggml-metal.h, so any Metal-enabled build fails to
compile. Add the same guarded include llama.cpp already uses.
