component_build_psa_accel_alg_ecdsa is subsumed by
component_test_psa_crypto_config_accel_ecdsa, which has the same
configuration and additionally runs the unit tests.

The bit length of m is leaked through through timing in ecp_mul_mxz().
Initially found by Manuel Pégourié-Gonnard on ecp_mul_edxyz(), which has
been inspired from ecp_mul_mxz(), during initial review of the EdDSA PR.
See: https://github.com/Mbed-TLS/mbedtls/pull/3245#discussion_r490827996
Fix that by using grp->nbits + 1 instead, which anyway is very close to
the length of m, which means there is no significant performance impact.

Disable non-crypto features that can't be called through the PSA API, as
well as algorithms that have no PSA interface.
This serves as a non-regression test for #6408 and #6409.

The PSA code needs pk_parse as well as pk_write for RSA keys. Fix#6409.
This is independent of PKCS#1v1.5 support. Fix#6408.

Break down the DER-encoded ASN.1 test data into its structure in a
comment and explain it, to make it easier to understand where the data
came from and how it is corrupted.

When pylint runs in parallel, it loses the ability to detect duplicated code
across modules. Duplicated code is usually a bad thing, so give pylint the
opportunity to let us know.
This makes pylint slightly slower, but going from 2 threads to 1 does not
make it anywhere close to twice as slow. On my machine, with Python 3.5,
pylint -j2 takes about 12s while single-threaded pylint takes about 16s
of wall clock time.

We had 4 identical copies of the check_repo_path function. Replace them by a
single copy in the build_tree module where it naturally belongs.

We were using absolute imports under the assumption that the /scripts
directory is in the path. This worked in normal use because every one of our
Python scripts either were in the /scripts directory, or added the /scripts
directory to the module search path in order to reference mbedtls_dev.
However, this broke things like
```
python3 -m unittest scripts/mbedtls_dev/psa_storage.py
```
Fix this by using relative imports.
Relative imports are only supposed to be used inside a package (Python
doesn't complain, but Pylint does). So make /scripts/mbedtls_dev a proper
package by creating __init__.py.

Do this in 2.28 just like it's done in the development branch, so that
code and command line usage that works on one branch doesn't surprisingly
fail on 2.28.

test_suite_directory can be changed by a command line option in the
development branch but not in 2.28. Align the simplified version here with a
change in the development version
("generate_*_tests.py --directory: fix handling of relative path").

We have Python code both for test code generation
(tests/scripts/generate_test_code.py) and now for test data generation.
Avoid the ambiguous expression "test generation".
This commit renames the Python module and adjusts all references to it. A
subsequent commit will adjust the documentation.
