doxygen: cleanup code for group_object_management

The cleanup involved three parts:

- Merging the standalone "/**@{*/" into
  "@addtogroup group_object_management"

- Changing "/**@}*/" to "/** @} group_object_management */",
  adding the group name makes it easier to find the matching "@{" part.

- Deleting the "@addtogroup" directive in "include/rtthread.h"
  because this header file doesn't have doxygen comments.
  All doxygen comments for function bodies are defined in "src/object.c".

Plus minor cleanup for group_hook in src/object.c.
