zip: add package for creating and extracting module zip files

zip provides three new functions:

* Create - build a zip from an abstract list of files, filtering out
  files in submodules and vendor directories. This is useful for
  filtering a zip produced by a VCS tool (as the go command does).
* CreateFromDir - build a zip from a directory. This is a convenience
  wrapper for Create.
* Unzip - extract a zip file, checking various restrictions.

A list of restrictions on module paths, versions, files within zips,
and size limits is included in the package documentation. Both Create
and Unzip enforce these restrictions.

Also: copied cmd/go/internal/txtar to internal/txtar for testing.
