sd-id128: add convenience functions to compare multiple sd_id128_t

Browse Source 
Similar to sd_bus_error_has_names() that was added in
2b07ec316a.

It is made inline in the hope that the compiler will be able to optimize
all the va_args boilerplate away, and do an efficient comparison when
the arguments are all constants.
