LU-18753 obdclass: remove obsolete dt functions

Remove:

dt_path_parser()
dt_store_resolve()
dt_store_open()
dt_reg_open()
dt_find_entry()
typedef dt_entry_func_t

These are not called anywhere.

Fixes: 29e98f581ab6 ("LU-2886 obdclass: remove obsoleted md_local_file.c")
Fixes: 29adfde10ff2 ("LU-2886 mdd: create local files using local_storage lib")
Fixes: 90d8e7fd2874 ("Land b_head_interop_disk  on HEAD (20081119_1314)")
