The DEFINE macro in asm-offsets.c (for all architectures) still generates

Commit ea59e7d780 ("xen/bitops: Cleanup and new infrastructure ahead of
rearrangements") introduced new violations on previously clean rules 20.9 and
20.12 (clean on ARM only, right now).
The first is introduced because CONFIG_CC_IS_CLANG in xen/self-tests.h is not
defined in the configuration under analysis. Using "defined()" instead avoids
relying on the preprocessor's behaviour upon encountering an undedfined identifier
and addresses the violation.
The violation of Rule 20.12 is due to "val" being used both as an ordinary argument
in macro RUNTIME_CHECK, and as a stringification operator.
No functional change.

Disable unnecessary configs for two cases:

2. By using tiny64_defconfig for non-randconfig builds.
Only configs which lead to compilation issues were disabled.
Remove lines related to disablement of configs which aren't affected

-# CONFIG_SCHED_CREDIT is not set
-# CONFIG_SCHED_RTDS is not set

-# CONFIG_SCHED_ARINC653 is not set
-# CONFIG_TRACEBUFFER is not set

Update argo.c to include asm/p2m.h directly, rather than on a transitive
dependency through asm/domain.h Update asm/p2m.h to include xen/errno.h,
rather than rely on it having included already.
CONFIG_XSM=n as it requires an introduction of:
* boot_module_find_by_kind()
* BOOTMOD_XSM
* struct bootmodule
* copy_from_paddr()
The mentioned things aren't introduced now.
CONFIG_BOOT_TIME_CPUPOOLS requires an introduction of cpu_physical_id() and
acpi_disabled, so it is disabled for now.
PERF_COUNTERS requires asm/perf.h and asm/perfc-defn.h, so it is
also disabled for now, as RISC-V hasn't introduced this headers yet.
LIVEPATCH isn't ready for RISC-V too and it can be overriden by randconfig,
so to avoid compilation errors for randconfig it is disabled for now.

Current issues with this test are:
- when the job timeout, the log file is lost as there is no chance to
run the `mv` command.
- GitLab job log is limited in size, so one usually have to download
the artifacts, which may be missing.
Use $GITLAB_CI to detect when the script is run as part of a GitLab
pipeline. GitLab will add "GITLAB_CI=true" in the environment
variables.
When run as part of $GITLAB_CI, ignore "dirty" worktree to allow to
write "build-each-commit-gcc.log", which can then be grabbed as
artifacts, even when the job timeout. The `git clean` command is
changed to keep those build logs.
When run as part of $GITLAB_CI, we will also store the build output in
a log file instead of writing it to stdout, because GitLab's job log
is limited. But we will write the log to stdout in case of error, so
we can find out more quickly why there's been an error.
This patch also make use of a GitLab feature, "log sections", which we
will collapse by default. One section per commit been built.
