Subject: [PATCH] [Feature] Add mmpose configs for compatibility with Hourglass
 model in ncnn backend (#1064)

* [FEATURE] add mmpose configs for compatibility with Hourglass model

[Motivation]
- The added configs are aim to support Hourglass pose-detection model in ncnn backend.
- Hourglass model needs explicit input shape with 256x256 or 384x384.
- Hourglass model can be quantitized to int8 successfully in ncnn backend.

[Complementary]
The mmpose config of Hourglass mode is in:
- https://github.com/open-mmlab/mmpose/blob/master/configs/body/2d_kpt_sview_rgb_img/topdown_heatmap/coco/hourglass52_coco_256x256.py
- https://github.com/open-mmlab/mmpose/blob/master/configs/body/2d_kpt_sview_rgb_img/topdown_heatmap/coco/hourglass52_coco_384x384.py
Quantitization results are shown in https://github.com/Qingrenn/mmdeploy-summer-camp/blob/main/week4/result.md

* Keep only one config (pose-detection_ncnn-int8_static-256x256.py) and remove the others.
