Fix T66955: Cannot delete data from file in outliner.

That switch on ID types had not been updated since quiet some time it’d
seem... Using the ID_Type enum type now, so this should not happen again
(compiler will yell at you if you forget to add here any new ID type ;) ).

Also had to change a bit the code layout then, to deal with fake NLA ID
type...

Note that for now, Screen IDs remain excluded from the ID menu usage,
due to T67004.
