Subject: [PATCH] Pin MDBX at last version with Win/Mac support (#3246)

## Issue Addressed

Newer versions of MDBX have removed Windows and macOS support, so this PR pins MDBX at the last working version to prevent an accidental regression via `cargo update`.

## Additional Info

This is a short-term solution, if our pinned version of MDBX turns out to be buggy we will need to consider backporting patches from upstream to our own fork.
