Asymmetric keys can't just be arbitrary byte strings: the public key
has to match the private key and the private key usually has
nontrivial constraints.
In order to have deterministic test data and not to rely on
cryptographic dependencies in the Python script, hard-code some test
keys.
In this commit, copy some test keys from test_suite_psa_crypto.data.

New Python module intended to gather knowledge about key types and
cryptographic mechanisms, such as the ability to create test data for
a given key type and the determination of whether an algorithm is
compatible with a key type.
This commit just creates a class for knowledge about key types.

At the moment it makes no difference, but it could if e.g. a new
algorithm was called 'foomask'.

By default, exclude macros whose numerical value is not a valid member
of the semantic type (e.g. PSA_ALG_xxx_BASE is not itself an
algorithm, only an intermediate value used to construct others). But
do include them with include_intermediate=True, which
generate_psa_constants.py does.

Create a directory mbedtls_dev intended to contain various Python
module for use by Python scripts located anywhere in the Mbed TLS
source tree.
Move get_c_expression_values and its auxiliary functions into a new
Python module mbedtls_dev.c_build_helper.
