Merge branch 'mbedtls'

Replace Crypto++ 5.6.2 with Mbed TLS 3.6.0

Newer compilers are starting to show the age of the crypto library we've
been using, as it is sometimes a pain to recompile compass lately.  So,
the tracked version of Crypto++ was at least due for an upgrade.

However, I plan to soon begin reimplementing compass in C.  So, I'm
taking this opportunity to first just migrate the cryptography library
to a newer C alternative.  This branch does so, and integrates its use
into the current C++ version of compass.

* mbedtls:
  Remove unnecessary exception handler catch block
  Refactor random password generation to use mbedtls entropy source
  Refactor SHA256 function to use mbedtls
  Refactor AES functions to use mbedtls
  Add Mbedtls library
  Remove Crypto++ library
