tests: introduce a compat-branches blacklist file

The idea behind this file is to have an easy and obvious mechanism for skipping
some tests on compatibility branches without modifying the test files
themselves or touching .gitlab-ci.yml.

Obviously, each compatibility branch can have different set of tests, and so
the contents of this file can be different on different branches.

This concept had actually existed in core for a long time, see
tests/blacklists/ directory.

Tests running `hg evolve` with in-memory merge.

Test evolving a single orphan

Test that in-memory evolve works when there are conflicts
and after continuing.
