Fix checkpoint_path unexpected argument (#1832)

-- This commit fixes the wrong Vulkan device being selected during
   runtime.
-- It also adds couple of IREE compilation flags to target specific
   Vulkan device.
-- It also changes the Vulkan device listing to be more in tune with
   lowering control flow.

+## CodeGen Setup using SHARK-server
+
+### Setup Server
+- clone SHARK and setup the venv
+- host the server using `python apps/stable_diffusion/web/index.py --api --server_port=<PORT>`
+- default server address is `http://0.0.0.0:8080`
+
+### Setup Client
+1. fauxpilot-vscode (VSCode Extension):
+- Code for the extension can be found [here](https://github.com/Venthe/vscode-fauxpilot)
+- PreReq: VSCode extension (will need [`nodejs` and `npm`](https://nodejs.org/en/download) to compile and run the extension)
+- Compile and Run the extension on VSCode (press F5 on VSCode), this opens a new VSCode window with the extension running
+- Open VSCode settings, search for fauxpilot in settings and modify `server : http://<IP>:<PORT>`, `Model : codegen` , `Max Lines : 30`
+
+2. Others (REST API curl, OpenAI Python bindings) as shown [here](https://github.com/fauxpilot/fauxpilot/blob/main/documentation/client.md)
+- using Github Copilot VSCode extension with SHARK-server needs more work to be functional.

+## How to run the model
+
+1.) Install all the dependencies by running:
+```shell
+pip install -r apps/language_models/langchain/langchain_requirements.txt
+sudo apt-get install -y libmagic-dev poppler-utils tesseract-ocr libtesseract-dev libreoffice
+```
+
+2.) Create a folder named `user_path` in `apps/language_models/langchain/` directory.
+
+Now, you are ready to use the model.
+
+3.) To run the model, run the following command:
+```shell
+python apps/language_models/langchain/gen.py --cli=True
+```
