libxl: idl: complete some enums in the IDL with their defaults

There are several enums in the IDL that are initialised to 0, while
the value 0 is not part of the enum itself. This creates problems for
language bindings generated from the IDL, such as the OCaml ones.

Added an explicit (0, "UNKNOWN") enum value where appropriate, or used
init_val to default to a sensible value.
