[Depends on #7948] Feat/bytes limit

[NesterovYehor]

Fixes #7954

This draft PR applies the SDK attribute value limit to the new BYTES attribute type.

The limiter has been implemented for trace and log attributes, ensuring values are truncated according to the configured attribute size limit (counting each byte as 1).

However, I was not able to identify the correct integration point for applying the same limit in metrics and resource attributes within this repository. I would appreciate guidance on where the limiter should be applied for those paths to ensure consistent behavior across signals.

The approach looks good 👍 I think we can try shipping support for bytes in the upcoming release.
