The environment variable PG_TEST_PG_COMBINEBACKUP_MODE has been
available since 35a7b288b9, but was not set by any built-in CI tasks.
This commit modifies two of the CI tasks to use the alternative modes,
to exercise the pg_combinebackup code.
The Linux task uses --copy-file-range, macOS uses --clone.
This is not an exhaustive test of combinations. The supported modes
depend on the operating system and filesystem, and it would be nice to
test all supported combinations. Right now we have just one task for
each OS, and it doesn't seem worth adding more just for this.

This converts
COPY_PARSE_PLAN_TREES
WRITE_READ_PARSE_PLAN_TREES
RAW_EXPRESSION_COVERAGE_TEST
into run-time parameters
debug_copy_parse_plan_trees
debug_write_read_parse_plan_trees
debug_raw_expression_coverage_test
They can be activated for tests using PG_TEST_INITDB_EXTRA_OPTS.
The compile-time symbols are kept for build farm compatibility, but
they now just determine the default value of the run-time settings.
Furthermore, support for these settings is not compiled in at all
unless assertions are enabled, or the new symbol
DEBUG_NODE_TESTS_ENABLED is defined at compile time, or any of the
legacy compile-time setting symbols are defined. So there is no
run-time overhead in production builds. (This is similar to the
handling of DISCARD_CACHES_ENABLED.)

Commit d01ce180 invented a new way to find the latest MacPorts version.
By bad luck, a new beta release has just been published, and it seems
to lack some packages we need. Go back to searching for this specific
version for now. We still search with a pattern so that we can find the
package for the running version of macOS, but for now we always look for
2.9.3. The code to do that had been anticipated already in a commented
out line, I just didn't expect to have to use it so soon...
Also include the whole MacPorts installation script in the cache key, so
that changes to the script cause a fresh installation. This should make
it a bit easier to reason about the effect of changes on cached state in
github accounts using CI, when we make adjustments.
Back-patch to 15, like d01ce180.

1. Previously we were using ghcr.io/cirruslabs/macos-XXX-base:latest
images, but Cirrus has started ignoring that and using a particular
image, currently ghcr.io/cirruslabs/macos-runner:sonoma, for github
accounts using free CI resources (as opposed to dedicated runner
machines, as cfbot uses). Let's just ask for that image anyway, to stay
in sync.
2. Instead of hard-coding a MacPorts installation URL, deduce it from
the running macOS version and the available releases. This removes the
need to keep the ci_macports_packages.sh in sync with .cirrus.task.yml,
and to advance the MacPorts version from time to time.
3. Change the cache key we use to cache the whole macports installation
across builds to include the OS major version, to trigger a fresh
installation when appropriate.
Back-patch to 15 where CI began.

gcc emits a warning for LLVM 14 code outside of our control. To avoid that,
update to a newer LLVM version. Do so both in the CompilerWarnings and normal
tasks - the latter don't fail, but the warnings make it more likely that we'd
miss other warnings.
We might want to backpatch this eventually. The higher priority right now is
to unbreak CI though - which is only broken on master, due to 0c3930d076
interacting badly with c8a6ec206a (mea culpa, I should have noticed this
before pushing, but I missed it due to another, independent CI failure).

Backpatch: 15-, where CI was added
Test all combinations of gssencmode, sslmode, whether the server
supports SSL and/or GSSAPI encryption, and whether they are accepted
by pg_hba.conf. This is in preparation for refactoring that code in
libpq, and for adding a new option for "direct SSL" connections, which
adds another dimension to the logic.
If we add even more options in the future, testing all combinations
will become unwieldy and we'll need to rethink this, but for now an
exhaustive test is nice.

The CI base image used to have a python3 with headers etc installed in PATH,
but doesn't anymore. Instead of relying on a specific version in the base
image, explicitly install one ourselves.
On 16 and HEAD this lead to a build without python support, but on 15 CI
failed, due to explicitly enabled python3 support.
Run the tests in a RAM disk. It's still a UFS file system and is backed
by 20GB of disk, but this avoids a lot of I/O. Even though we disable
fsync, our tests do a lot of directory manipulations, some of which
force file system meta-data to disk and flush slow device write caches
on UFS. This was a bottleneck preventing effective scaling beyond 2
CPUs.
Now we can use 4 CPUs like on other OSes, for a huge speedup.

When running all (or just many) of our tests, a significant portion of both
CPU time and IO is spent running initdb. Most of those initdb runs don't
specify any options influencing properties of the created data directory.
Avoid most of that overhead by creating a "template" data directory, alongside
the temporary installation. Instead of running initdb, pg_regress and tap
tests can copy that data directory. When a tap test specifies options to
initdb, the template data directory is not used. That could be relaxed for
some options, but it's not clear it's worth the effort.
There unfortunately is some duplication between pg_regress.c and Cluster.pm,
but there are no easy ways of sharing that code without introducing additional
complexity.

Backpatch: 15-, where CI support was added
cirrus-ci will soon restrict the amount of free resources every user gets (as
have many other CI providers). For most users of CI that should not be an
issue. But e.g. for cfbot it will be an issue.
To allow configuring different resources on a per-repository basis, introduce
infrastructure for overriding the task execution environment. Unfortunately
this is not entirely trivial, as yaml anchors have to be defined before their
use, and cirrus-ci only allows injecting additional contents at the end of
.cirrus.yml.
To deal with that, move the definition of the CI tasks to
.cirrus.tasks.yml. The main .cirrus.yml is loaded first, then, if defined, the
file referenced by the REPO_CI_CONFIG_GIT_URL variable, will be added,
followed by the contents of .cirrus.tasks.yml. That allows
REPO_CI_CONFIG_GIT_URL to override the yaml anchors defined in .cirrus.yml.
Unfortunately git's default merge / rebase strategy does not handle copied
files, just renamed ones. To avoid painful rebasing over this change, this
commit just renames .cirrus.yml to .cirrus.tasks.yml, without adding a new
.cirrus.yml. That's done in the followup commit, which moves the relevant
portion of .cirrus.tasks.yml to .cirrus.yml. Until that is done,
REPO_CI_CONFIG_GIT_URL does not fully work.
The subsequent commit adds documentation for how to configure custom compute
resources to src/tools/ci/README
