Disables unnecessary configs for two cases:
1. By utilizing EXTRA_FIXED_RANDCONFIG for randconfig builds (GitLab CI jobs).
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
compilation:
 -# CONFIG_SCHED_CREDIT is not set
 -# CONFIG_SCHED_RTDS is not set
 -# CONFIG_SCHED_NULL is not set
 -# CONFIG_SCHED_ARINC653 is not set
 -# CONFIG_TRACEBUFFER is not set
 -# CONFIG_HYPFS is not set
 -# CONFIG_SPECULATIVE_HARDEN_ARRAY is not set

To allow CONFIG_ARGO build happy it was included <asm/p2m.h> to <asm/domain.h>
as ARGO requires p2m_type_t ( p2m_ram_rw ) and declaration of
check_get_page_from_gfn() from xen/p2m-common.h.

Also, it was included <xen/errno.h> to asm/p2m.h as after the latter was
included to <asm/domain.h> the compilation error that EINVAL, EOPNOTSUPP
aren't declared started to occur.

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.

CPU_BOOT_TIME_CPUPOOLS requires an introduction of cpu_physical_id() and
acpi_disabled, so it is disabled for now.

Changes in V8:
 - disabled CPU_BOOT_TIME_CPUPOOLS as it requires an introduction of cpu_physical_id() and acpi_disabled.
 - leave XSM disabled, add explanation in the commit message.
 - drop HYPFS as the patch was provided to resolve compilation issue when this condif is enabled for RISC-V.
 - include asm/p2m.h to asm/domain.h, and xen/errno.h to asm/p2m.h to drop ARGO config from
   tiny64_defconfing and build.yaml.
 - update the commit message.
---
Changes in V7:
 - Disable only configs which cause compilation issues.
 - Update the commit message.
---
Changes in V6:
 - Nothing changed. Only rebase.
---
Changes in V5:
 - Rebase and drop duplicated configs in EXTRA_FIXED_RANDCONFIG list
 - Update the commit message
---
Changes in V4:
 - Nothing changed. Only rebase
---
Changes in V3:
 - Remove EXTRA_FIXED_RANDCONFIG for non-randconfig jobs.
   For non-randconfig jobs, it is sufficient to disable configs by using the defconfig.
 - Remove double blank lines in build.yaml file before archlinux-current-gcc-riscv64-debug
---
Changes in V2:
 - update the commit message.
 - remove xen/arch/riscv/Kconfig changes.

While XSM and BOOT_TIME_CPUPOOLS are covered in the description, I struggle
with PERF_COUNTERS: What's missing there (besides trivial asm/perfc.h and
asm/perfc_defn.h)? As to LIVEPATCH: I suppose there ought to be HAS_LIVEPATCH
allowing arch-es to indicate whether they support that.

I think only them are needed. I can wrap them by #ifdef
CONFIG_PERF_COUNTERS to check.

We could wrap asm/perfc.h by #ifdef CONFIG_PERF_COUNTERS, but it seems
it should be a separate patch and until there is no such patch it
should be disabled.

Hmm, I haven't seen HAS_LIVEPATCH. I think the intention was that it is
enough to have a default value, but it can be overridden.
   config LIVEPATCH
   	bool "Live patching support"
   	default X86
   ....
