rust-nodemap: automatically use the rust index for persistent nodemap

The persistent nodemap requires the rust index to be used to provides any gains.
So we automatically enable it for revlog using the persistent nodemap. We keep
it off for other revset because now that the rust revlog fully initialise the
nodemap using it everywhere introduce a fairly significant regression (eg: hg
diff moving from 0.8s to 2.3s on mozilla-try)

Create an empty repo:

  $ hg init a
  $ cd a

Try some commands:

  $ hg log
  $ hg grep wah
  [1]
  $ hg manifest
  $ hg verify
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  checked 0 changesets with 0 changes to 0 files

Check the basic files created:

  $ ls .hg
  00changelog.i
  cache
  requires
  store
  wcache

Should be empty:

  $ ls .hg/store

Poke at a clone:

  $ cd ..
  $ hg clone a b
  updating to branch default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd b
  $ hg verify
