Suzy Mueller caa95bb40b internal/lsp: add completions of unimported std lib pkgs
Unimported packages may be suggested as completion items. Since these
are not yet imported, they should be ranked lower than other candidates.

They also require an additional import statement to be valid, which is
provided as an AdditionalTextEdit.

Adding this import does not use astutil.AddNamedImport, to avoid
editing the current ast and work even if there are errors. Additionally,
it can be hard to determine what changes need to be made to the source
document from the ast, as astutil.AddNamedImport includes a merging
pass. Instead, the completion item simply adds another import
declaration.
