stream-clone: add a explicit set list requirements relevant to stream clone

This set explicitly lists all the requirements that "stream clone" will
preserve. Any other one will not be preserved.

The role of listing the relevant one was previously filled by
`repo.supportedformat`, but it seems clearer to use that such global and
explicit set. The `repo.supportedformat` attribute will be cleaned up in a later
changeset

The true meaning of `repo.supportedformat` vs `repo._basesupported` was lost
over time so, the content is currently bad. For example, `dirstate-v2` is
currently considered relevant to the stream clone, or internal phase is
missing. We kept the same content in this changeset and we will fix them later.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.

Notes for packagers
===================

Mercurial ships a copy of the python-zstandard sources. This is used to
provide support for zstd compression and decompression functionality. The
module is not intended to be replaced by the plain python-zstandard nor
is it intended to use a system zstd library. Patches can result in hard
to diagnose errors and are explicitly discouraged as unsupported
configuration.
