Add Asset Download Action and update Drush command to support --asset_id or --media_id flags

Problem/Motivation

As a admin, I want a dedicated asset download action and updated Drush commands support for --asset_id and --media_id flags in the Acquia DAM module, so that assets can be downloaded directly via a module action and individual assets or media entities can be targeted precisely from the command line.

Acceptance Criteria

Asset Download Action

• A new "asset download action" is implemented and available within the Acquia DAM module.
• The action successfully triggers the download of the specified Acquia DAM asset.

Drush Command Arguments

• The designated Drush command is updated to accept --asset_id=[ID] or --media_id=[ID] as optional parameters.
• When --asset_id is passed, the command executes its logic exclusively on the provided DAM asset ID.
• When --media_id is passed, the command executes its logic exclusively on the provided Drupal media entity ID.
• Appropriate validation and error handling are in place if an invalid ID is provided.
