mmapindex: move the 'mmapindexthreshold' option out of experimental

The option is useful and should be advertised more. We move it out of
experimental as a first step. The `storage` section is selected as this is
related to how the storage is accessed. A new 'performance' section might be
more appropriate.

We move from 'mmapindexthreshold` to `mmap-threshold` as non-index item are
also suitable for mmap (eg: the rev-branch-cache).

If relevant, we can introduce sub-option `mmap-threshold.revlog-index` later.
