malloc: Refactor redzone and sanitizer handling

malloc_large() duplicates redzone and KASAN handling that is also
present in malloc() and malloc_domainset().  Refactor the
implementations to reduce this a bit.

Also normalize KMSAN map handling: make malloc() and malloc_domainset()
consistent, and do not update the KMSAN shadow map, as we can rely on
UMA and kmem_malloc() to handle that.
