Cover react/renderer/runtimescheduler with Stable API guards (#58150)

Summary:

Classifies `react/renderer/runtimescheduler:runtimescheduler` as a "for frameworks" target under the three-tier C++ stable API visibility model. Consumers that opt into `RN_STRICT_API` now get a warning if they include its headers directly, which they can acknowledge with `RN_ALLOW_FRAMEWORKS`; without that flag the guards are inert, so no existing build changes behaviour.

`RuntimeScheduler_Legacy.h` gets its guard above the `RCT_REMOVE_LEGACY_ARCH` block so it is still evaluated when the legacy architecture is compiled out.
