🚀 [firebase_ai] Support Files API as an alternative to InlineDataPart

[ReplayAppTeam]

Hello,

I've experienced a very strange issue:

When I ask Gemini to extract some information from a video file it takes way too long 20 - 25 seconds for videos which are 30 seconds max and take around 1-5 mb.

I was supplying the video file as bytes using InlineDataPart as described in the docs https://firebase.google.com/docs/ai-logic/analyze-video?api=dev

It was unusual to me that it takes that long especially because the Gemini Android app gives way faster response.

Then I decided to try the REST API and what I noticed there is an alternative way of supplying files to Gemini and thats via Files API.

It is described here https://ai.google.dev/gemini-api/docs/video-understanding#rest_1

Usage of the REST API resulted in 2x faster Gemini response.

I can't tell why exactly but the only noticeable difference I see is the way video file is supplied in the library and when working with REST so my guess is that's what made it faster.
