When testing a function that is supposed to be constant-flow, we declare the
inputs as constant-flow secrets with TEST_CF_SECRET. The result of such a
function is itself a constant-flow secret, so it can't be tested with
comparison operators.
In TEST_EQUAL, TEST_LE_U and TEST_LE_S, declare the values to be compared as
public. This way, test code doesn't need to explicitly declare results as
public if they're only used by one of these macros.

This comment (which used to be attached to the implementation, and should
not have been moved to the header file) is incorrect: the library function
mbedtls_mpi_read_string preserves leading zeros as desired, but does not
create a zero-limb object for an empty string.

Other programs/*/Makefile are only created by CMake, but programs/fuzz has
its own Makefile in the repository. Fixes#6247.

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

BaseTarget-derived targets are now added to TestGenerator.targets in
initialization. This reduces repeated code in generate_xxx_tests.py
scripts which use this framework.

When generating combinations of values, `itertools.combinations` will
not allow inputs to be repeated. This is replaced so that cases where
input values match are generated, i.e. ("0", "0").

Version of pylint used in CI does not recognize abstract subclasses of
BaseTarget, so disable warning in these abstract classes.

Previous implementation mixed the test case generation and the
recursive generation calls together. A separate method is added to
generate test cases for the current class' test function. This reduces
the need to override generate_tests().
