begin cleanup of malloc porting layer

1. Merge some of the allocators into sk_malloc_flags by redefining a flag to mean zero-init
2. Add more private helpers to simplify our call-sites (and handle some overflow mul checks)
3. The 2-param helpers rely on the saturating SkSafeMath::Mul to pass max_size_t as the request,
which should always fail.
