Remove mash/runner and its exclusive dependencies

This removes //mash/runner and most of //mash, which was only used by
the //mash/runner environment. This environment is no longer maintained
or in active use by developers.

For now the Launchable mojom interface is left as the sole component in
this directory (specifically in mash/public) because it has quite a few
references around the tree.
