mtmd : read LFM2 tiling params from GGUF metadata (#30840)

• mtmd : read LFM2 tiling params from GGUF metadata

Write min_tiles, max_tiles, tile_size and max_pixels_tolerance from
processor_config.json when converting LFM2-VL mmproj, read them in clip.cpp
with the previous constants as defaults. do_image_splitting=false maps to
min_tiles=max_tiles=1 (no tiling).

Rebased version of #25524, original implementation by Michael DM (@michael-dm).
