Modify memory mapping attribute flags

This updates caching, access and control flags for the provided page-aligned memory region.

Calling this function on a region which was not mapped to begin with is undefined behavior. However system memory implicitly mapped at boot time is supported.

@param addr Page-aligned memory region base virtual address @param size Page-aligned memory region size @param flags K_MEM_PERM_, K_MEM_MAP_ control flags. @return 0 for success, negative error code otherwise.
