community[patch]: Add Progress bar to HuggingFaceEmbeddings (#16758)

- **Description:** Adds a function parameter to HuggingFaceEmbeddings
called `show_progress` that enables a `tqdm` progress bar if enabled.
Does not function if `multi_process = True`.
  - **Issue:** n/a
  - **Dependencies:** n/a
