contrib: add a script for adding vendored type stubs to typeshed

I really hate this, but pytype doesn't support PEP 561 and doesn't seem to have
the equivalent of `MYPYPATH` to point to custom stubs.  Ignoring the vendored
stubs isn't necessarily harmful, but pytype has been choking on the vendored
attr package after pytype 2022.03.29 with errors like this:

    File "/mnt/c/Users/Matt/hg/mercurial/linelog.py", line 52, in __iter__: Built-in function iter was called with the wrong arguments [wrong-arg-types]
             Expected: (collection: bytearray)
      Actually passed: (collection: mercurial.thirdparty.attr._make._CountingAttr)

    File "/mnt/c/Users/Matt/hg/mercurial/dirstateutils/v2.py", line 143, in pack: Built-in function len was called with the wrong arguments [wrong-arg-types]

This is essentially the same hack we've been using in TortoiseHg to add the
vendored PyQt5 stubs.  What I don't understand is pytype *still* generates *.pyi
files under .pytype/pyi/mercurial/thirdparty/attr, even when the package is
explicitly ignored in the pytype command line args.  But it avoids the errors,
which means we aren't stuck on pytype==2022.03.29.
