Ash 732a657694 Change Config to make fastmem_pointer of zero valid.
This changes Dynarmic::A32/A64::Config to store fastmem_pointer in
a std::optional<uintptr_t>, allowing the user to pass a zero base
address for the guest memory, which can be used to effectively
implement a shared address space between the host and the guest.
