Core: Drop custom `copymem`/`zeromem` defines

We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f66391327b2967a20a89c3627e1dd6e84eb.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.
