fix: set max resolution for common video codecs

[ferrarimarco]

Changes

Instead of relying on the max resolution for the H264 codec decoder as a
global setting when computing device capabilities, set the max supported
resolution for the most common video codecs by querying the decoder.

Video codecs that support this are: AVC (H264), HEVC (H265), AV1.

This change avoids unnecessary transcodings because, on some devices,
the AVC decoder might support a lower maximum resolution compared to
other decoders that the device supports. For example, if the AVC decoder
supports up to 2K resolution decoding, and the HEVC supports up to 4K
resolution decoding, Jellyfin would have transcoded a 4K HEVC media
stream.

I tested this on my setup, and, after this change, 4K HEVC media files all direct play instead of transcoding.

Thanks for digging deeper into the issue. I think it's worth adding the maximum resolution for multiple codecs, although the way you did it is not entirely correct.

A "device profile" is a big JSON document with rules about what the client is able to play and what it is not able to play. It should be device specific, not format specific. By which I mean: instead of detecting the codec type for a given media stream and building a device profile from that, we should always add the maximum resolution for all (common) codecs.

Right now we only have the codecProfile for h264 in this block:

	// Limit video resolution support for older devices
	codecProfile {
		type = CodecType.VIDEO

		conditions {
			ProfileConditionValue.WIDTH lowerThanOrEquals maxResolution.width
			ProfileConditionValue.HEIGHT lowerThanOrEquals maxResolution.height
		}
	}

To make it codec specific we can just add a single line (after the type line):

		codec = Codec.Video.H264

Then we can also add the same block for other codecs.

Thanks for the tip.

I'll refactor the pr as you suggest.

@nielsvanvelzen thanks for your review. I refactored the PR as you advised. Can you please take another look?

Tested and working.

Thanks
