Rebecca Stambler 0cdb17d11b internal/lsp: treat the module root as the workspace root, if available
This change expands the scope of a workspace to the whole module, if the
user is in module mode. This means that diagnostics will appear and will
be updated for the whole module, even if the user only opens a
subdirectory. Similarly, references and other such queries will always
return consistent results, no matter which directory the user opens.

A new "root" field is added to the view. This is either the view's
folder or its module root. Almost all uses of view.folder have been
changed to view.root.

Updates golang/go#32394
