MbedTLS linking issues with HashLink binaries on Linux

Since the binaries are currently compiled on Ubuntu 18.04 which has mbedtls 2.8.0, ssl.hdll is linked to `libmbedtls.so.10`. Ubuntu 20.04 has `libmbedtls.so.12`, and Ubuntu 22.04 has `libmbedtls.so.14`, which is the current version for MbedTLS 2. This means that if hashlink continues to link mbedtls dynamically, the binaries cannot work on all versions of Linux at once. Even MbedTLS 3 seems to change the .so name with every minor release: https://abi-laboratory.pro/?view=timeline&l=mbedtls

We could start linking mbedtls statically, but that means the mbedtls version will be stuck at whatever hashlink was compiled with, which is a security concern.

This is possibly the root cause of issues like #590.
