[FEATURE] Improve setup_models.py to build engines

[eliteprox]

Feature type

Build

Describe the feature

setup_models.py should both download and build engines

Motivation

Currently there is a loose dependency between ai-runner and comfystream with models.yaml and dl_checkpoints.sh. A change to models.yaml can break dl_checkpoints and the ai-runner CI.

dl_checkpoints already reuses setup_models.py to download the models https://github.com/livepeer/ai-runner/blob/9e21e45480bf3112388f5b4b6bfb11df3ea51522/runner/dl_checkpoints.sh#L101-L111, however it doesn't compile them.

dl_checkpoints separately compiles tensorrt engines and assumes the model files are present. https://github.com/livepeer/ai-runner/blob/9e21e45480bf3112388f5b4b6bfb11df3ea51522/runner/dl_checkpoints.sh#L136-L145

models.yaml can be updated to include the necessary parameters to compile the engines so that build_trt is only ran for models which were also downloaded by the config.
