[PATCH RFC v6 07/12] target/riscv: Support setting external interrupt by KVM

Extend riscv_cpu_update_mip() to support setting external interrupt by KVM. It will call kvm_riscv_set_irq() to change the IRQ state in the KVM module When kvm is enabled and the MIP_SEIP bit is set in "mask" In addition, bacause target/riscv/cpu_helper.c is used to TCG, so move riscv_cpu_update_m
