KVM_GET_REG_LIST will dump all register IDs that are available to
KVM_GET/SET_ONE_REG and It's very useful to identify some platform
regression issue during VM migration.

Patch 1-7 re-structured the get-reg-list test in aarch64 to make some
of the code as common test framework that can be shared by riscv.

Patch 8 move reject_set check logic to a function so as to check for
different errno for different registers.
Patch 9 move finalize_vcpu back to run_test so that riscv can implement
its specific operation.
Patch 10 change to do the get/set operation only on present-blessed list.
Patch 11 add the skip_set facilities so that riscv can skip set operation
on some registers.
Patch 12 enabled the KVM_GET_REG_LIST API in riscv.
patch 13 added the corresponding kselftest for checking possible
register regressions.

The get-reg-list kvm selftest was ported from aarch64 and tested with
Linux v6.4 on a Qemu riscv64 virt machine.

---
Changed since v4:
  * Rebase to v6.4
  * Address Andrew's suggestions and comments:
      Added skip_set concept
      Updated errno check logic
      Modified finalize_vcpu as weak function
