matcher: fix issues regex flag contained in pattern (issue6759)

Python 3.11 is now enforcing that flag must be at the beginning of the regex

This creates a serious regression for people using Python 3.11 with an hgignore
using flag in a "relre" pattern.

We now detect any flags in such pattern and "prepend" our ".*" pattern after them.

In addition, we now insert the flag in the regexp to only affect the pattern we
are rewriting. Otherwise, the regex built from the combined pattern would these
flags in the middle of it anyway.

As a side effect of this last change, we fix a bug… before this change regex
flag in a pattern would affect all combined patterns. That was bad and is not
longer the case.

The Rust code needs to be updated to fix that very bug, but we will do it in
another changeset.

====================================
Testing head checking code: Case A-6
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category A: simple case involving a branch being superseded by another.
TestCase 6: multi-changeset branch, split on multiple other, (base on its own branch), same number of head

.. old-state:
..
.. * 2 branch (1-changeset, and 2-changesets)
..
.. new-state:
..
.. * 1 new branch superseding the base of the old-2-changesets-branch,
.. * 1 new changesets on the old-1-changeset-branch superseding the head of the other
..
.. expected-result:
..
.. * push allowed
