Not sure why this didn't break completely, but still works with this change at least.

I guess a quarter of the embeddings were still correct which is enough to produce relatively ok results. Btw even the bounding box tests from earlier are good.

* model : Granite docling + Idefics3 preprocessing (SmolVLM) (ggml-org#16206)

* feat: Add granite-docling conversion using trillion pretokenizer

Branch: gabe-l-hart/GraniteDocling

Signed-off-by: Gabe Goodhart <ghart@us.ibm.com>

* feat: Add tiling support for idefices3 in clip.cpp

This should likely be moved into llava_uhd::get_slice_instructions, but for
now this avoids disrupting the logic there.

* feat: Partial support for full templating for idefics3 in mtmd

There are still errors encoding some of the image chunks, but the token
sequence now matches transformers _almost_ perfectly, except for the double
newline before the global image which shows up as two consecutive newline
tokens instead of a single double-newline token. I think this is happening
because the blocks are tokenized separately then concatenated.

* feat: Fully working image preprocessing for idefics3 w/ resize and slicing

* feat: Parse the preprocessor config's longest side and add it to the mmproj hparams

Branch: GraniteDocling

Signed-off-by: Gabe Goodhart <ghart@us.ibm.com>

* fix: Use the longest side instead of size * scale_factor

For Granite Docling, these come out to the same value, but that was just a
conicidence.
