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.

# This file is used on compatibility branches to skip tests that for one reason
# or another are not applicable or simply incompatible with older versions of
# Mercurial.
#
# On default and stable branch this file should not list any test files. It's
# only supposed to be populated on compability branches.
