The field `late_deser` in `ZIF_ABAPGIT_DEFINITIONS=>ty_metadata` is obsolete:
```abap
TYPES:
BEGIN OF ty_metadata,
class TYPE string,
version TYPE string,
late_deser TYPE abap_bool, " refactor: can be removed later. replaced by steps
delete_tadir TYPE abap_bool,
ddic TYPE abap_bool,
END OF ty_metadata .
```
The PR removes the remaining usage with one exception: `ZCL_ABAPGIT_OBJECTS_BRIDGE->GET_DESERIALIZE_STEPS` still depends on the field. In order to remove it completely, the plug-in interface `zif_abapgitp_plugin` (https://github.com/abapGit/abapGit-Plugins/blob/master/src/zif_abapgitp_plugin.intf.abap) will have to be changed.
