mount: move directory cache state to a side map to shrink InodeEntry

The mount keeps an InodeEntry alive for every inode the kernel references.
On a mount that is almost entirely regular files, each entry carried the full
directory readdir-cache bookkeeping (four time.Time fields plus counters),
bloating it to 152 bytes whether or not the inode was a directory.

Move that state into a dirState held in a side map keyed by inode, and drop the
isDirectory bool: an inode is a directory iff it has a dirState. InodeEntry is
now just paths + nlookup at 32 bytes, landing in a smaller Go allocator size
class; on a mount with tens of millions of cached file inodes that is several GB
less resident heap. As a side effect the readdir-cache scan helpers iterate only
directories instead of every inode.
