File write streams inherit the default byte-stream highWaterMark. The fixed 16 KiB value became stale when that default changed. Also document the Windows-specific byte-stream default. Signed-off-by: umuoy1 <burningdian@gmail.com>

The
fs.createWriteStream()andfilehandle.createWriteStream()docs still listed a fixed 16 KiB default. These streams inherit the default byte-stream highWaterMark, which is 64 KiB on non-Windows platforms and 16 KiB on Windows.Update the fs docs to reference
stream.getDefaultHighWaterMark()and clarify the platform-specific defaults in the stream docs.
