## What does this PR do?
**Type of change:**
Bug fix
**Overview:**
1. The diffusion_trt.py needs the dynamic_shapes when running trtexec
for engine building. A previous change altered the format of
dynamic_shapes, fix it here.
2. the dynamic_shapes logic gets cleaned up. The existing logic is very
confusing
3. recover min-batch_size config for some pipelines. Previously some
pipelines set the min batch_size to be > 1, which was odd, so a previous
change sets them to be 1, but it turns out the oddity has a reason, the
trt engine building fails with the altered batch_size min/opt, thus
recover them.
