commit: pull substate writing into workingctx

This pulls the logic for committing dirty subrepos and writing out the
substate during localrepo.commit() into the workging context.

This is part of a larger refactoring effort to unify working-copy
commits and in-memory commits.  Among other things, this will allow
for optimizations in graft, rebase, and similar commands.
