What Does This Do

Adds primitive setters to DDSpanContext

Motivation

TagMap can store primitive in its entries directly without boxing
But to take advantage of TagMap, we need to avoid auto-boxing in instrumentation
DDSpan already had primitive setters, but those call into DDSpanContext which didn't have primitive setters

Additional Notes

This code has been structured to behave optimally for both LegacyTagMap (e.g. HashMap) which boxes and OptimizedTagMap which avoids boxing

Right now, the tracer will still end up boxing in the serialization code, but this change at least moves the boxing out of the instrumentation / application critical path. Boxing during serialization will be addressed in a separate pull request.
