workspace: make WorkspaceLoader::load() return WorkspaceLoadError

Browse source 
I plan to make `RepoLoader::init()` return a `Result`, which means
that `WorkspaceLoader::load()` will need to return more kinds of
errors. Making it return `WorkspaceLoadError` is a good start. By also
extracting a function for converting `WorkspaceLoadError` to
`CommandError`, we can reuse a the handling of `PathError` in
`cli_util`.
