[PATCH v3 030/114] target/riscv: add kvm stubs source set

[Yonggang Luo <luoyonggang@xxxxxxxxx>]

- Add riscv_stubs_ss and kvm-stub.c, matching the ARM target_stubs_arch
  pattern (has_mp_state returns false; other entry points are
  g_assert_not_reached).
- Register target_stubs_arch += {'riscv': riscv_stubs_ss}.
- Leave target_arch / target_system_arch in place; next change can
  move RISC-V onto target_common_system_arch.
