Introduce new APIs in essp_heap_caps.h: - heap_caps_walk() - heap_caps_walk_all() Those functions are triggering a callback for all blocks (allocated or free) of memory present in heaps meeting the set of capabilities passed as parameter (or all heaps for heap_caps_walk_all() function) test_walker.c added to test the new functionality in test_apps/heap_test/
