88c8e3a0e4 github actions: Fix test-one-commit when parent of head is merge commit (Ryan Ofsky)
Pull request description:
Instead of figuring out the commit *after* the last merge and rebasing on that with a ~1 suffix, just figure out the last merge commit directly and rebase on it. This way, if HEAD happens to be a merge commit, the rebase just succeeds immediately without blank variables or errors.
Explanation of the problem from https://github.com/bitcoin/bitcoin/pull/28497#issuecomment-1743430631:
> The problem is that the PR only contains a one commit after the last merge, so the job _should_ be skipped, but the `pull_request.commits != 1` check is not smart enough to skip it because the PR is based on another PR and has merge ancestor commits. So specifically what happens is that after HEAD~ is checked out, the new HEAD is a merge commit, so the range `$(git log --merges -1 --format=%H)..HEAD` is equivalent to HEAD..HEAD, which is empty, so the `COMMIT_AFTER_LAST_MERGE` variable is empty and the rebase command fails.
Note: In the current version of this PR, the "test each commit" job is skipped, because this PR only contains a single commit. But I manually verified the code works in earlier versions of the PR that included dummy commits.

fa5356cd49 ci: Limit test-each-commit to --max-count=6 (MarcoFalke)
fafcd2e9ef ci: Add test-each-commit task (MarcoFalke)
Pull request description:
Currently, if a pull request has more than one commit, previous commits may fail to compile, or may fail the tests. This is problematic, because it breaks git-bisect, or worse.
Fix this by adding a CI task for this.

The exact distro name should not be important. Also, it is easy to find
out, if needed. Thus, remove it to avoid bloat and maintenance overhead
having to keep it in sync.
fa26387769 ci: Refactor: Remove CI_USE_APT_INSTALL (MarcoFalke)
Pull request description:
Seems odd to use `CI_USE_APT_INSTALL == no` as an alias for `CI_OS_NAME == macos`. Fix this by removing the alias.
Also, for github CI:
* restore MAKEJOBS to the same value as in cirrus.yml.
* remove cirrus-only PACKAGE_MANAGER_INSTALL.
* remove redundant TEST_RUNNER_TIMEOUT_FACTOR
* Add M1 link

I've noticed the "Bug" label being added redundantly fairly frequently.
I think this might be due to github's templates.
All in all, the link in https://github.com/bitcoin/bitcoin/issues/new/choose
to open a regular issue is a bit hidden from sight. Direct people's
attention to it.
