feat: add TencentARC PhotoMaker support (#179)

* first efforts at implementing photomaker; lots more to do

* added PhotoMakerIDEncoder model in SD

* fixed soem bugs; now photomaker model weights can be loaded into their tensor buffers

* added input id image loading

* added preprocessing inpit id images

* finished get_num_tensors

* fixed a bug in remove_duplicates

* add a get_learned_condition_with_trigger function to do photomaker stuff

* add a convert_token_to_id function for photomaker to extract trigger word's token id

* making progress; need to implement tokenizer decoder

* making more progress; finishing vision model forward

* debugging vision_model outputs

* corrected clip vision model output

* continue making progress in id fusion process

* finished stacked id embedding; to be tested

* remove garbage file

* debuging graph compute

* more progress; now alloc buffer failed

* fixed wtype issue; input images can only be 1 because issue with transformer when batch size > 1 (to be investigated)

* added delayed subject conditioning; now photomaker runs and generates images

* fixed stat_merge_step

* added photomaker lora model (to be tested)

* reworked pmid lora

* finished applying pmid lora; to be tested

* finalized pmid lora

* add a few print tensor; tweak in sample again

* small tweak; still not getting ID faces

* fixed a bug in FuseBlock forward; also remove diag_mask op in for vision transformer; getting better results

* disable pmid lora apply for now; 1 input image seems working; > 1 not working

* turn pmid lora apply back on

* fixed a decode bug

* fixed a bug in ggml's conv_2d, and now > 1 input images working

* add style_ratio as a cli param; reworked encode with trigger for attention weights

* merge commit fixing lora free param buffer error

* change default style ratio to 10%

* added an option to offload vae decoder to CPU for mem-limited gpus

* removing image normalization step seems making ID fidelity much higher

* revert default style ratio back ro 20%

* added an option for normalizing input ID images; cleaned up debugging code

* more clean up

* fixed bugs; now failed with cuda error; likely out-of-mem on GPU

* free pmid model params when required

* photomaker working properly now after merging and adapting to GGMLBlock API

* remove tensor renaming;  fixing names in the photomaker model file

* updated README.md to include instructions and notes for running PhotoMaker

* a bit clean up

* remove -DGGML_CUDA_FORCE_MMQ; more clean up and README update

* add input image requirement in README

* bring back freeing pmid lora params buffer; simply pooled output of CLIPvision

* remove MultiheadAttention2; customized MultiheadAttention

* added a WIN32 get_files_from_dir; turn off Photomakder if receiving no input images

* update docs

* fix ci error

* make stable-diffusion.h a pure c header file

This reverts commit 27887b6.

* fix ci error

* format code

* reuse get_learned_condition

* reuse pad_tokens

* reuse CLIPVisionModel

* reuse LoraModel

* add --clip-on-cpu

* fix lora name conversion for SDXL

+#### Using PhotoMaker to personalize image generation
+
+You can use [PhotoMaker](https://github.com/TencentARC/PhotoMaker) to personalize generated images with your own ID. 
+
+**NOTE**, currently PhotoMaker **ONLY** works with **SDXL** (any SDXL model files will work).
+
+Download PhotoMaker model file (in safetensor format) [here](https://huggingface.co/bssrdf/PhotoMaker). The official release of the model file (in .bin format) does not work with ```stablediffusion.cpp```.
+
+- Specify the PhotoMaker model path using the `--stacked-id-embd-dir PATH` parameter. 
+- Specify the input images path using the `--input-id-images-dir PATH` parameter. 
+  - input images **must** have the same width and height for preprocessing (to be improved)
+
+In prompt, make sure you have a class word followed by the trigger word ```"img"``` (hard-coded for now). The class word could be one of ```"man, woman, girl, boy"```. If input ID images contain asian faces, add ```Asian``` before the class
+word.
+
+Another PhotoMaker specific parameter:
+
+- ```--style-ratio  (0-100)%```: default is 20 and 10-20 typically gets good results. Lower ratio means more faithfully following input ID (not necessarily better quality).
+
+Other parameters recommended for running Photomaker:
+
+- ```--cfg-scale 5.0```
+- ```-H 1024```
+- ```-W 1024```
+
+If on low memory GPUs (<= 8GB), recommend running with ```--vae-on-cpu``` option to get artifact free images.
+
+Example:
+
+```bash
+bin/sd -m ../models/sdxlUnstableDiffusers_v11.safetensors  --vae ../models/sdxl_vae.safetensors --stacked-id-embd-dir ../models/photomaker-v1.safetensors --input-id-images-dir ../assets/examples/scarletthead_woman -p "a girl img, retro futurism, retro game art style but extremely beautiful, intricate details, masterpiece, best quality, space-themed, cosmic, celestial, stars, galaxies, nebulas, planets, science fiction, highly detailed" -n "realistic, photo-realistic, worst quality, greyscale, bad anatomy, bad hands, error, text" --cfg-scale 5.0  --sampling-method euler -H 1024 -W 1024 --style-ratio 10 --vae-on-cpu -o output.png
