core: use full synchronization on macOS

On macOS, fsync() flushes data to the drive without requesting a flush
of its write cache. Xlog close paths and cooperative fsync/fdatasync
calls therefore do not ensure that data reaches permanent storage.

The macOS fsync(2) manual documents the stronger guarantee:

> The F_FULLFSYNC fcntl asks the drive to flush all buffered data to
> permanent storage.

This patch uses F_FULLFSYNC for synchronous and asynchronous xlog
synchronization and for fio.fsync() and fio.fdatasync() on macOS.

Part of #13330
