Merge #2689 #2690

2689: Use mimalloc as the global allocator r=Kerollmops a=loiclec

milli has switched its global allocator to mimalloc already, and we have seen some performance gains as a result. Furthermore, we can use mimalloc as the global allocator on all platforms whereas jemalloc was only activated on Linux. 

This PR brings mimalloc to Meilisearch as well. 

2690: Add LTO and codegen-units=1 to release compile options r=Kerollmops a=loiclec

This PR brings Meilisearch's release compile options in line with milli (see https://github.com/meilisearch/milli/pull/606 ). 

Adding LTO and codegen=units=1 will make compile times longer, but they also speed up the final binary significantly.
