[roll] Roll fuchsia Reland "[fxfs] Clean up dirty bytes when dropping unflushed files."

This reverts commit 4617b8aeafcab0639ced06964b16f87c4723ea41.

Reason for revert: Replaced ZX_VMO_OP_COMMIT in profile replay with ZX_VMO_OP_PREFETCH which will stop marking pages dirty in the background.

> > [fxfs] Clean up dirty bytes when dropping unflushed files.
> >
> > When files are modified after unlink, dropping the last reference
> > purposely doesn't flush the file since the contents are about to be
> > purged. This is the case for dropping unnamed temporary files as well.
> >
> > When pages are dirtied past the end of file they cannot be safely
> > dropped since there may be an appending write that touches those pages
> > between. So these dirty ranges are tracked through the file lifetime and
> > dropped during close. Previously those bytes were leaked in the
> > accounting in the VolumesDirectory, now they're reported back to the
> > VolumesDirectory to stop tracking them when they get dropped.
> >
> > Adds in a debug assert to check that there are no pages left that need
> > flushing when the vmo is being dropped, and any dirty pages that don't
> > need to be flush, are marked as clean in the accounting since they're
> > going away.
