typing: explicitly type some `mercurial.util` eol code to avoid @overload

Unlike the previous commit, this makes a material difference in the generated
stub file- the `pycompat.identity()` aliases generated an @overload like this:

    @overload
    def fromnativeeol(a: _T0) -> _T0: ...

... which might fail to detect a bad argument, like str.  This drops the
@overload for the 3 related methods, so there's a single definition for each.

The `typelib.BinaryIO_Proxy` is used for subclassing (the same as was done in
8147abc05794), so that it is a `BinaryIO` type during type checking, but still
inherits `object` at runtime.  That way, we don't need to implement unused
abstract methods.

  $ hg init test
  $ cat >hgweb.cgi <<HGWEB
  > #!$PYTHON
  > from mercurial import demandimport; demandimport.enable()
  > from mercurial.hgweb import hgweb
  > from mercurial.hgweb import wsgicgi
  > application = hgweb(b"test", b"Empty test repository")
  > wsgicgi.launch(application)
  > HGWEB
  $ chmod 755 hgweb.cgi

Check that non-ASCII bytes roundtrip correctly.
