Szabolcs Nagy c076a0bc69 malloc: Only support zeroing and not arbitrary memset with mtag
The memset api is suboptimal and does not provide much benefit. Memory
tagging only needs a zeroing memset (and only for memory that's sized
and aligned to multiples of the tag granule), so change the internal
api and the target hooks accordingly.  This is to simplify the
implementation of the target hook.
