Separate file is added for classes used to generate cases for tests
in bignum_core.function. Common elements of the BignumOperation class
are added to classes in a new common file, for use across files.

When writing the new .data file, first write the new content, then replace
the target. This way, there isn't a temporary state in which the file is
partially written. This temporary state can be misleading if the build is
interrupted. It's annoying if you're watching changes to the output and the
changes appear as emptying the file following by the new version appearing.
Now interrupted builds don't leave a file that appears to be up to date but
isn't, and when watching the output, there's a single transition to the new
version.

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.

The option to --directory was intended to be relative to the current
directory when the script is invoked, which is the intuitive behavior. But
this was not implemented correctly, and it was actually interpreted relative
to the mbedtls root (which the script chdir's into). Fix this.

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.

Previous changes used the docstring of the test_generation module,
which does not inform a user about the script.

Arg parse improved to update the input params path relative to
mbedtls_root passed, if the other params are not explicitly passed.

Function names can be provided against entry points.

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

TLS uses it to derive the session secret. The algorithm takes a serialized
point in an uncompressed form, extracts the X coordinate and computes
SHA256 of it. It is only expected to work with P-256.
Fixes#5978.
