Subject: [PATCH] Override H264/AVC High 10 Profile Level 5.2 support for some
 devices (#935)

## Description
Several Fire TV devices natively support H264/AVC High 10 Profile Level
5.2 according to [their
specs](https://developer.amazon.com/docs/device-specs/device-specifications-fire-tv-streaming-media-player.html),
but the `MediaCodecInfo` doesn't return this support.

So this PR adds an override for the known devices that support this
which prevents unnecessary transcoding.

### Related issues
Closes #786

### Testing
Verified on a Fire TV 4k Max 2nd Gen

## Screenshots
N/A

## AI or LLM usage
