Using this new library it is now possible to leverage the memory
attribute property 'zephyr,memory-attr' to define and create a set of
memory heaps from which the user can allocate memory from with certain
attributes / capabilities.
When the CONFIG_MEM_ATTR_HEAP option is set, every region marked with
one of the memory attributes listed in
include/zephyr/dt-bindings/memory-attr/memory-attr-sw.h is added to a
pool of memory heaps used for dynamic allocation of memory buffers with
certain attributes.
