Don't inject timeline hooks unless React supports profiling #23151

This gives DevTools a way to detect whether the current React renderer supports Timeline profiling. (Version alone isn't enough to detect this, neither is general profiling support– since these two are controlled by different feature flags.)

Relates to #22529.

getLaneLabelMap and injectProfilingHooks are already optional parameters (not injected by earlier versions of react) so it's safe to conditionally include them.
