Subject: [PATCH 3/4] switch to using EVP_PKEY_derive instead of DH_compute_key
in DH (#5972)
* switch to using EVP_PKEY_derive instead of DH_compute_key in DH
Where checks are occurring is changing in OpenSSL 3.0 and this makes it
easier to be consistent (and is the API we should be using anyway). The
tests change because EVP_PKEY_derive now verifies that we have shared
parameters, which the test previously only verified by asserting that
the derived keys didn't match
* review feedback
* type ignores required for typeerror tests. some day i will remember this

Subject: [PATCH 4/4] Use well-defined enum representation
Python 3.10 changed enum's object and string representation. PyCA
cryptography now uses a custom subclass of enum.Enum() will well-defined
__repr__ and __str__ from Python 3.9.
