dependencies: rm pyaes from requirements 
Since #6014, pyaes is not really needed anymore.

As we currently require either one of pycryptodomex or cryptography,
even if pyaes is available, it will not be used.
We could strip it out completely from crypto.py...

In any case, pyaes is still pulled in by some hw wallet dependencies indirectly;
but the core library no longer depends on it.
