localrepo: move repo creation logic out of localrepository.__init__ (API)

It has long bothered me that local repository creation is handled as
part of localrepository.__init__. Upcoming changes I want to make
around how repositories are initialized and instantiated will make
the continued existence of repository creation code in
localrepository.__init__ even more awkward.

localrepository instances are almost never constructed directly:
instead, callers are supposed to go through hg.repository() to obtain
a handle on a repository. And hg.repository() calls
localrepo.instance() to return a new repo instance.

This commit teaches localrepo.instance() to handle the create=True
logic. Most of the code for repo construction has been moved to a
standalone function. This allows extensions to monkeypatch the function
to further customize freshly-created repositories.

A few calls to localrepo.localrepository.__init__ that were passing
create=True were converted to call localrepo.instance().

.. api:: local repo creation moved out of constructor

   ``localrepo.localrepository.__init__`` no longer accepts a
   ``create`` argument to create a new repository. New repository
   creation is now performed as part of ``localrepo.instance()``
   and the bulk of the work is performed by
   ``localrepo.createrepository()``.
