Platform-independent platform abstraction

This is the platform-independent portion of the standard library’s platform abstraction layer, whereas std::sys is the platform-specific portion.

The relationship between std::sys_common, std::sys and the rest of std is complex, with dependencies going in all directions: std depending on sys_common, sys_common depending on sys, and sys depending on sys_common and std. This is because sys_common not only contains platform-independent code, but also code that is shared between the different platforms in sys. Ideally all that shared code should be moved to sys::common, and the dependencies between std, sys_common and sys all would form a dag. Progress on this is tracked in #84187.
