[Feature] Support Side Adapter Network (#3232)
## Motivation
Support SAN for Open-Vocabulary Semantic Segmentation
Paper: [Side Adapter Network for Open-Vocabulary Semantic
Segmentation](https://arxiv.org/abs/2302.12242)
official Code: [SAN](https://github.com/MendelXu/SAN)

## Modification
- Added the parameters of backbone vit for implementing the image
encoder of CLIP.
- Added text encoder code.
- Added segmentor multimodel encoder-decoder code for open-vocabulary
semantic segmentation.
- Added SideAdapterNetwork decode head code.
- Added config files for train and inference.
- Added tools for converting pretrained models.
- Added loss implementation for mask classification model, such as SAN,
Maskformer and remove dependency on mmdetection.
- Added test units for text encoder, multimodel encoder-decoder, san
decode head and hungarian_assigner.

## Use cases
### Convert Models
**pretrained SAN model**
The official pretrained model can be downloaded from
[san_clip_vit_b_16.pth](https://huggingface.co/Mendel192/san/blob/main/san_vit_b_16.pth)
and
[san_clip_vit_large_14.pth](https://huggingface.co/Mendel192/san/blob/main/san_vit_large_14.pth).
Use tools/model_converters/san2mmseg.py to convert offcial model into
mmseg style.
`python tools/model_converters/san2mmseg.py <MODEL_PATH> <OUTPUT_PATH>`

**pretrained CLIP model**
Use the CLIP model provided by openai to train SAN. The CLIP model can
be download from
[ViT-B-16.pt](https://openaipublic.azureedge.net/clip/models/5806e77cd80f8b59890b7e101eabd078d9fb84e6937f9e85e4ecb61988df416f/ViT-B-16.pt)
and
[ViT-L-14-336px.pt](https://openaipublic.azureedge.net/clip/models/3035c92b350959924f9f00213499208652fc7ea050643e8b385c2dac08641f02/ViT-L-14-336px.pt).
Use tools/model_converters/clip2mmseg.py to convert model into mmseg
style.
`python tools/model_converters/clip2mmseg.py <MODEL_PATH> <OUTPUT_PATH>`

### Inference
test san_vit-base-16 model on coco-stuff164k dataset
`python tools/test.py
./configs/san/san-vit-b16_coco-stuff164k-640x640.py
<TRAINED_MODEL_PATH>`

### Train
test san_vit-base-16 model on coco-stuff164k dataset
`python tools/train.py
./configs/san/san-vit-b16_coco-stuff164k-640x640.py --cfg-options
model.pretrained=<PRETRAINED_MODEL_PATH>`
