Justus Klausecker 3af5f81e11 std.heap.ArenaAllocator: fix end_index memory ordering ...

This prevents a race between `alloc` and `free` where T1 receives memory
from `alloc` that is semantically about to be freed by T2 and still being
accessed, but the `free` is already visible to T1. Using acquire-release
here guarantees that any `free` is only published after all accesses to
the memory being freed have already happened.
