mtmd: Add Gemma3n multimodal support with MobileNetV5 vision encoder (#18256) * Add Gemma3nVisionModel - MobileNetV5 vision encoder convertor to convert_hf_to_gguf.py. Add gemma3n to vision projectors in gguf-py/gguf/constants.py. * Add mobilenetv5 impl * Fix comments, remove unused vars * Fix permute and remove transpose of projection weights * Fix comments, remove debugging prints from hf_to_gguf * 1. Hard-code image_mean = 0 and image_std = 1 2. Use available tensor mapping logic 3. Remove redundant chat template replacement of soft tokens placeholder with media placeholder * 1. Move mobilenetv5 helpers declarations to `clip_graph_mobilenetv5` struct and definitions to mobilenetv5.cpp 2.Remove unused `clip_is_gemma3n` func declarations and definitions 3. Remove redundant `rescale_image_u8_to_f32` func and use `normalize_image_u8_to_f32` with zero mean and unit std 4. Calculate n_patches using image_size / patch_size * Remove obsolete comments * - convert_hf_to_gguf.py & constants.py & tensor_mapping.py: Use explicit mapping: Custom map for double indexed blocks and tensor_mapping.py for rest - convert_hf_to_gguf.py: Unsqueeze Stem Bias and Layer scale tensors to correct shape while converting to gguf - mobilenetv5.cpp: Remove explicit reshaping of Stem Bias and Layer scale which are now handled while converting to gguf, replace fprintf with LOG_* - clip.cpp: Remove unused embedding and hard_emb_norm tensor loading * - Rename tensors to v.conv..., v.blk..., v.msfa... to better align with already existing terminology * Fix stem conv bias name * Remove explicit handling of bias term for stem conv * - Change order of addition in "project_per_layer_inputs" to support broadcasting of vision inp_per_layer - Simplify the vision embeddings path of "get_per_layer_inputs" to output [n_embd_altup, n_layer, 1], broadcastable * clean up conversion script * fix code style * also preserve audio tensors * trailing space * split arch A and V * rm unused gemma3 func * fix alignment --------- Co-authored-by: Xuan Son Nguyen <son@huggingface.co>
