doxygen: cleanup code for group_thread_management

The cleanup involved three parts:

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

- Changing "/**@}*/" to "/** @} group_thread_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 other .c files.

  Note, we remian two doxygen comments for rt_thread_inited_hookproto_t
  and rt_thread_idle_sethook in the "include/rtthread.h".
  rt_thread_inited_hookproto_t is really defined here.
  For rt_thread_idle_sethook, please see FIXME comment for reason.
