posix: Add self-contained pthread spinlock

Turn pthread_spinlock_t into a self-contained object. On uni-processor
configurations, interrupts are disabled in the lock/trylock operations
and the previous interrupt status is restored in the corresponding
unlock operations. On SMP configurations, a ticket lock is a acquired
and released in addition.

The self-contained pthread_spinlock_t object is defined by Newlib in
<sys/_pthreadtypes.h>.

typedef struct {

struct _Ticket_lock_Control _lock;
uint32_t _interrupt_state;

} pthread_spinlock_t;

This implementation is simple and efficient. However, this test case of
the Linux Test Project would fail due to call of printf() and sleep()
during spin lock ownership:

https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_spin_lock/1-2.c

There is only limited support for profiling on SMP configurations.

Delete CORE spinlock implementation.

Update #2674.

725	* @brief Maximum priority configuration.

727	* This configures the maximum priority value that
728	* a task may have.
729	*
730	* The following applies to the data space requirements
731	* of the Priority Scheduler.
732	*
733	* By reducing the number of priorities in a system,
734	* the amount of RAM required by RTEMS can be significantly
735	* reduced. RTEMS allocates a Chain_Control structure per
736	* priority and this structure contains 3 pointers. So
737	* the default is (256 * 12) = 3K on 32-bit architectures.
738	*
739	* This must be one less than a power of 2 between
740	* 4 and 256. Valid values along with the application
741	* priority levels and memory saved when pointers are
742	* 32-bits in size are:
743	*
744	* + 3, 2 application priorities, 3024 bytes saved
745	* + 7, 5 application priorities, 2976 bytes saved
746	* + 15, 13 application priorities, 2880 bytes saved
747	* + 31, 29 application priorities, 2688 bytes saved
748	* + 63, 61 application priorities, 2304 bytes saved
749	* + 127, 125 application priorities, 1536 bytes saved
750	* + 255, 253 application priorities, 0 bytes saved
751	*
752	* It is specified in terms of Classic API priority values.
