logging: init backend id regardless of autostart
The `id` is basically a compile-time constant. Setting it every
time the backend is enabled is unnecessary. Instead, set it on
`z_log_init()` regardless of whether or not it requires to be
`autostart`ed.
Fixes an issue where the `filter_get`/`filter_set`
accessed the wrong index and displayed the wrong log level when
user accesses the status of an uninitialized backend via:
`log backend <uninitialized_backend> status`.
Also fixes an issue when user tries to list the backends via:
`log list_backends`, where all uninitialized backends will have
ID = 0.
