SERVER-50984 Add CollectionPtr to replace usage of const Collection*
It implements a yieldable interface that is used to re-load the
Collection pointer from the catalog after a yield that released locks.
With lock-free reads and copy-on-write on Collection instances releasing
locks without notifying an AutoGetCollection at a higher level may cause
its pointers to dangle if a MODE_X writer installs a new Collection
instance in the catalog.
CollectionPtr should be passed by const reference so a yield can notify
all the way up.
