Description of change
This PR adds global allocator wrapper counting allocation metrics (alloc, dealloc, peak) per thread. It uses unstable feature
thread_local(it's the only reasonable way,thread_local!macro can't be used) which is guarded behind feature"flamegraph-alloc". The allocation stats are shown in rendered SVG.Links to any relevant issues
Part of #8694.
