perf(tracer): improve performance of DefaultContextProvider #14920

Description

Two small tweaks to improve the overhead of DefaultContextProvider.

  • Replace isinstance(item, Span) with type(item) is Span`
    • Skip the isinstance check because we should only ever have this exact class and not a subclass
  • Remove calls to Span.finished which is a computed property

Testing

Risks

perf(tracer): improve performance of DefaultContextProvider (#14920)
a34849f 
## Description

Two small tweaks to improve the overhead of DefaultContextProvider.

- Replace `isinstance(item, Span) with `type(item) is Span`
- Skip the `isinstance` check because we should only ever have this
exact class and not a subclass
- Remove calls to `Span.finished` which is a computed property
