New python module to encode a PSA key for storage

Construct an object given the attributes and material for a PSA crypto key
and get the Mbed TLS storage representation.

The code to generate the storage representation was written based on the
specification in docs/architecture/mbed-crypto-storage-specification.md,
without looking at the code.

The data in the unit tests is from the AES-128 format_storage_data_check
test case in test_suite_psa_crypto_persistent_key.data, tweaked manually.

This commit creates a basic framework for using symbolic values for
attributes, but does not yet implement obtaining the corresponding numerical
values from an external source.
