When a macOS Hypervisor.framework call fails which is checked by assert_hvf_ok(), Qemu exits printing the error value, but not the location in the code, as regular assert() macro expansions would. This change turns assert_hvf_ok() into a macro similar to other assertions, which expands to a call to the corresponding _impl() function together with information about the expression that failed the assertion and its location in the code. Additionally, stringifying the numeric hv_return_t code is factored into a helper function that can be reused for diagnostics and debugging outside of assertions.
