Introduce ifuncs and resolvers for functions pertinent to the malloc interface on the AArch64 target: malloc, calloc, free, realloc, memalign, valloc, pvalloc, posix_memalign, aligned_alloc, free_sized, free_aligned_sized, malloc_usable_size. A target can define the USE_MULTIARCH_MALLOC macro. In this case it must provide alternative aliases for the malloc functions that point to the ifuncs. This implementation respects the --disable-multi-arch configure flag. If multi-arch support is disabled, the generic aliases are used on aarch64. This patch contains aarch64-specific resolvers. At this point they return core implementations but in the future they can be changed to support for features, e.g. to handle memory tagging. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
