Support allocating stack from separate heap (#267)

The change adds support for allocating task stacks from separate heap.
When configSTACK_ALLOCATION_FROM_SEPARATE_HEAP is defined as 1 in
FreeRTOSConfig.h, task stacks are allocated and freed using
pvPortMallocStack and vPortFreeStack functions. This allows the
application writer to provide a separate allocator for task stacks.

When configSTACK_ALLOCATION_FROM_SEPARATE_HEAP is defined as 0, task
stacks are allocated and freed using FreeRTOS heap functions
pvPortMalloc and vPortFree.

For backward compatibility, configSTACK_ALLOCATION_FROM_SEPARATE_HEAP
defaults to 0.
