Rewrite MbedTLS codepaths to use the modern PSA APIs
...
This also fixes an issue that caused audio decryption to fail on MbedTLS 3.x.
Closes #142

Don't depend on outputDataLength to be initialized with mbedTLS
...
OpenSSL has no such requirement, so MbedTLS breakages snuck in.

Optimize OpenSSL backend to avoid redundant reinitialization
...
It is best to pass as few parameters to EVP_*Init_ex() as possible.
Passing a key, IV, or cipher will cause redundant work to happen behind
the scenes as OpenSSL doesn't check whether they have actually changed.
This avoids a malloc()/free() and redoing AES key expansion for every
message that is encrypted and decrypted.
