Make select jsinspector tracing implementation headers private

Summary:
Mark the following tracing headers as private instead of for-frameworks. All of them are implementation details of React Native's tracing infrastructure, and no for-frameworks header includes them:

- `EventLoopReporter` is an RAII helper the runtime scheduler uses to report event loop task and microtask phases to the performance tracer. It is only used by `EventLoopReporter.cpp` and `RuntimeScheduler_Modern.cpp`.
- `RuntimeSamplingProfileTraceEventSerializer` turns a runtime sampling profile into trace events. It is only used by tracing sources, `TracingAgent.cpp` and its own unit test.
- `TraceEventSerializer` serializes trace events to `folly::dynamic`. It is only used by tracing sources and `TracingAgent.cpp`.
- `TraceEventGenerator` builds trace events for the performance tracer and the host profile serializer. It is only used by tracing sources and was already not exported in Buck.
- `ProfileTreeNode` is an auxiliary tree used to build the profile and deduplicate identical frames. It is only used by `RuntimeSamplingProfileTraceEventSerializer.cpp` and its own unit test.
- `Timing.h` defines the tracing clock origin and the conversions from `HighResTimeStamp` and `HighResDuration` to trace event microseconds. It is only used by tracing sources and a tracing unit test.

`TracingAgent.h` included `Timing.h` without using it; that include is removed.

React Native's own targets define `RN_BUILDING`, so the private guard does not affect them.
