Instead of an LRU strategy for cap-ing span attributes, comply with the specification and drop last added. To do this, the attributesmap is replaced with a slice of attributes.

Unify duplicated code. Fix deduplication algorithm. Fix droppedAttributes to always be returned, even if the span has no attributes.

This is an alternate implementation to #2555. It is preferred to that PR because it realizes similar gains but maintains the order of attributes (in the order the user added them).

Testing performance comparison
This looks to have considerable memory and allocation reduction and faster computations when compared to
main.
