Replace system allocator with mimalloc (#3087)

# Description
I looked more into the supposed memory leak and noticed that the system
allocator requires unreasonable amounts of memory compared to
[mimalloc](https://www.google.com/search?client=firefox-b-d&q=mimalloc+github)
so I replaced it for all the binaries.

Here we can see the memory footprint of the api pod with `mimalloc`
(green) and the system allocator (yellow). The served traffic is the
same but the system allocator continues to require more and more memory
- probably because it's worse at dealing with memory fragmentation than
`mimalloc`.
