[PATCH v2 00/25] CI: run "make [test]" directly, use $GITHUB_ENV

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

A re-roll of my improvements my series to simplify the CI setup a lot
(see diffstat), much of it was dealing with constraints that went away
with Travis et al. CI for this series (OSX runners failing for
unrelated reasons):

    https://github.com/avar/git/actions/runs/2040223909

For a much more detailed summary of how the output looks before/after
see v1[].

This series heavily conflicts with Johannes's
js/ci-github-workflow-markup in "seen", but in the v1 I suggested
basing that series on top of this one, because it can benefit a lot
from these simplifications.

I'll reply to this series with a proposed rebasing of that series on
top of this one, which allows for removing almost all of its changes
to "ci/" with no harm to its end-goals, i.e. the splitting up of
"make" and "make test" output is something it'll get for free from
this series.

Junio: Since that series has been stalled on still-outstanding
performance issues for a couple of months I was hoping we could queue
this instead, and perhaps in addition if Johannes approves of the
proposed re-roll on top of his.

There's some forward progress on the performance issues (this[2] reply
of Victoria Dye's from yesterday), but fully resolving those will
probably take a bit...

Whereas even though this one is relatively large I don't think there's
anything controversial here. The one concern that's been raised has
been Johannes's objection to removing some of the dead Azure code
(which was needed to move forward here). I asked how he'd prefer to
move forward with that in [3], but there hasn't been a reply to that
in >1 month.

I think just removing it is OK, we can always bring it back if needed,
and doing so is actually going to be simpler on top of this since the
CI is now less special, and leans more heavily on the logic of our
normal build process.

      ## Commit message ##
    -    CI: stop over-setting the $CC variable
    +    CI: set CC in MAKEFLAGS directly, don't add it to the environment
     
    -    As detailed in 2c8921db2b8 (travis-ci: build with the right compiler,
    -    2019-01-17) the reason we started using $CC in $MAKEFLAGS as opposed
    -    to setting it in the environment was due to Travis CI clobbering $CC
    -    in the environment.
    +    Rather than pass a "$CC" and "$CC_PACKAGE" in the environment to be
    +    picked up in ci/lib.sh let's instead have ci/lib.sh itself add it
    +    directly to MAKEFLAGS.
     
    -    We don't need to set it unconditionally to accomplish that, but rather
    -    just have it set for those jobs that need them. E.g. the "win+VS
    -    build" job confusingly has CC=gcc set, even though it builds with
    -    MSVC.
    +    Setting CC=gcc by default made for confusing trace output, and since a
    +    preceding change to carry it and others over across "steps" in the
    +    GitHub CI it's been even more misleading.  E.g. the "win+VS build" job
    +    confusingly has CC=gcc set, even though it builds with MSVC.
    +
    +    Let's instead reply on the Makefile default of CC=cc, and only
    +    override it for those jobs where it's needed. This does mean that
    +    we'll need to set it for the "pedantic" job, which previously relied
    +    on the default CC=gcc in case "clang" become the default on that
    +    platform.
     
         This partially reverts my 707d2f2fe86 (CI: use "$runs_on_pool", not
         "$jobname" to select packages & config, 2021-11-23), i.e. we're now
