Subject: Revert "perf: use jemalloc as global allocator (#18957)" (#19187)

This reverts commit 798c1ad0f1de80ff0e7196b6140a3f74e31fe111.

Reverting because this change caused a spike in memory usage, but we
can't fully realise gains from lower GC pressure from more optimal
malloc/ free provided by "jemalloc".

We might revisit the topic in future.
