Corrected the module kernel stack size so it no longer overstates the usable stack (#701)
The module manager recorded tx_thread_module_kernel_stack_size as the raw
TXM_MODULE_KERNEL_STACK_SIZE constant, but the end of the kernel stack is aligned
downwards to an eight-byte boundary while _txm_module_manager_object_allocate only
guarantees ULONG alignment. The recorded size could therefore overstate the usable
stack by up to seven bytes. The scheduler copies this value into tx_thread_stack_size
whenever a user mode module thread enters the kernel, so the overstated value is
visible to RTOS-aware debuggers and to anything built on it.
The size is now derived from the aligned end minus the start. Also documented that
TX_ENABLE_STACK_CHECKING is not supported for module threads.
