localrepo: use setters instead of constructor for commit metadata

Instead of including the commit metadata in the constructor for the
context actually used for commit, we later use setters to update the
context with that metadata.  This will allow us to use the commitable
context for another sanity checks, and will make it easier to split
the logic in localrepo.commit() into multiple functions.

This is part of a larger refactoring effort to make memctx easier to
use.
