xen/riscv: Update Kconfig in preparation for a full Xen build

Disable 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

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.
