LU-9216 config: move config types into lustre_idl.h

LU-9216 config: move config types into lustre_idl.h

Move config type values CONFIG_T_XXX into lustre_idl.h since they
will be put on wire when reading config log for IR and nodemap.

Add missing wire checks for mgs_nidtbl_entry, mgs_config_body and
mgs_config_res.

Redefine CONFIG_SUB_XXX for the sub clds attached on config log.
