fix: Support file uploads for OpenAI/Azure in LiteLLM

Browse Source

This change expands the supported file MIME types and introduces provider-specific handling for file uploads. For providers like OpenAI and Azure, inline file data is now uploaded via `litellm.acreate_file` to obtain a `file_id`, which is then used in the message content. Other providers continue to use base64 encoded file data. Affected functions have been updated to be asynchronous
