From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>

Create a new riscv_cpu_experimental_exts[] to store the non-ratified
extensions properties. Once they are ratified we'll move them back to
riscv_cpu_extensions[].

riscv_cpu_add_user_properties() and riscv_cpu_add_kvm_properties() are
changed to keep adding non-ratified properties to users.
