sparse: move post commit actions into core

sparse: move post commit actions into core

Instead of wrapping committablectx.markcommitted(), we inline
the call into workingctx.markcommitted().

Per smf's review, workingctx is the proper location for this
code, as committablectx is the shared base class for it and
memctx. Since this code touches the working directory, it belongs
in workingctx.
