bundle2: move bundle2 config option to section "experimental"

We highlight the fact that this is experimental by moving it to an "experimental"
section, and we match the config name with the server capability name
`bundle2-exp`.

folding and creating no new change doesn't break:
-------------------------------------------------

folded content is dropped during a merge. The folded commit should properly disappear.

  $ hg add file

Test corner case where folded revision is separated from its parent by a
dropped revision.
