c-user: Obsolete CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE

Browse Source 
The CONFIGURE_HAS_OWN_INIT_TASK_TABLE and
CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE are the last *_HAS_OWN_*
configuration options.  These two options are probably unused, see also:

* https://lists.rtems.org/pipermail/users/2019-April/033129.html

* https://lists.rtems.org/pipermail/users/2019-April/033130.html

Removing them simplifies the configuration. If there is a real user need
which shows up after the removal, we can resurrect them on demand.

Using CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE would have required the
use of the undocumented CONFIGURE_POSIX_INIT_THREAD_TABLE_NAME and
CONFIGURE_POSIX_INIT_THREAD_TABLE_SIZE configuration options.

Close #3874.

CONSTANT:
``CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE``
DATA TYPE:
Boolean feature macro.
RANGE:
Defined or undefined.
DEFAULT VALUE:
This is not defined by default.
DESCRIPTION:
``CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE`` is defined if the user wishes
to define their own POSIX API Initialization Threads Table. This table
should be named ``POSIX_Initialization_threads``.
NOTES:
This is a seldom used configuration parameter. The most likely use case is
when an application desires to have more than one initialization task.
