stream-clone: filter possible missing requirements using all supported one

The `supportedformat` requirements is missing some important requirements and it
seems better to filter out with all requirements we know, not just an
"arbitrary" subset.

The `supportedformat` set is lacking some important requirements (for example
`revlog-compression-zstd`). This is getting fixed on default (for Mercurial 6.1)

However, fixing that in 6.1 means the stream requirements sent over the wire
will contains more items. And if we don't apply this fix on older version, they
might end up complaining about lacking support for feature they actually support
for years.

This patch does not fix the deeper problem (advertised stream requirement
lacking some of them), but focus on the trivial part : Lets use the full set of
supported requirement for looking for unsupported ones.

This patch should be simple to backport to older version of Mercurial and
packager should be encouraged to do so.

This is a graft of d9017df70135 from default.

============================================
Testing obsolescence markers push: Cases B.1
============================================

Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).

This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.

Category B: pruning case
TestCase 1: Prune on non-targeted common changeset

B.1 Prune on non-targeted common changeset

Initial

  $ setuprepos B.1
  creating test repo for test case B.1
  - pulldest

  cd into `main` and proceed with env setup
  $ cd main
  $ mkcommit A
  $ mkcommit B

make both changeset known in remote

  $ hg push -qf ../pushdest
