Tim Orling c6f79207f8 python3-cryptography: move from meta-python
* inherit new setuptools_rust class (which inherits new pyo3 class, which
  inherits cargo and python3-dir).
* RDEPENDS on python3-pytest-subtests for ptest
* Copy pyproject.toml for ptest as it defines the pytest.marker(s) needed
* Use 'cargo bitbake' to generate the crate:// SRC_URIs
   - Needed some hacks to the Cargo.toml in src/rust/ to make this work (probably
     only package.repository was strictly required):

     [package]
     description = "cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions."
     homepage = "https://github.com/pyca/cryptography"
     repository = "https://github.com/pyca/cryptography"

* Add patches to src/rust/Cargo.toml to fix cargo errors including  pem version
* Add check-memfree.py to ptest to check for sufficient free memory
