target/riscv: add satp_mode profile support

'satp_mode' is a requirement for supervisor profiles like RVA22S64.
User-mode/application profiles like RVA22U64 doesn't care.

Add 'satp_mode' to the profile description. If a profile requires it,
set it during cpu_set_profile(). We'll also check it during finalize()
to validate if the running config implements the profile.
