locking/Kconfig: Add LOCK_DEBUGGING_SUPPORT to make it more readable 

There are a couples of lock debugging Kconfig options that depends on
the following support options:

 - TRACE_IRQFLAGS_SUPPORT
 - STACKTRACE_SUPPORT
 - LOCKDEP_SUPPORT

That makes those lock debugging options harder to read and understand.
So a new LOCK_DEBUGGING_SUPPORT option is added that is equivalent to
the above three options together. That makes the Kconfig.debug file
more readable.
