Skip type erasure in trace_future/trace_block when no tracer is set

[Dandandan]

Summary

• Add fast path to trace_future and trace_block that skips the Box<dyn Any + Send> type erasure and downcast pipeline when no custom JoinSetTracer is registered (the common case)
• When GLOBAL_TRACER is not set, returns the future/closure directly with minimal boxing overhead

Background

Profiling ClickBench queries showed trace_future's type erasure overhead accounted for ~12% of total CPU time. Even with the NoopTracer, every spawned task was paying the cost of:

1. Boxing the result as Box<dyn Any + Send> (type erasure)
2. Passing through the tracer (noop)
3. Downcasting back from Box<dyn Any + Send> to T
4. Double-boxing the future with .boxed()

Benchmark results (ClickBench, single iteration)

Notable improvements:

Query	Before (ms)	After (ms)	Change
Q3	74.9	48.0	-36.0%
Q18	2517.5	2032.8	-19.3%
Q19	54.9	43.2	-21.3%
Q32	4497.6	4225.1	-6.1%
Q33	2671.2	2497.9	-6.5%
Total	43272.9	42092.2	-2.7%

Test plan

• cargo test -p datafusion-common-runtime passes
• cargo clippy -p datafusion-common-runtime --all-targets --all-features -- -D warnings clean
• CI passes
