Although negative zero is officially unsupported, we've had bugs related to
it in the past. So do test functions with a negative zero input.
There will likely be cases where we don't want to accept negative zero as if
it was valid, because it's too hard to handle. We'll add exceptions on a
case by case basis.
For the functions that are currently tested by the generated tests, the new
test cases pass.

The bignum module does not officially support "negative zero" (an
mbedtls_mpi object with s=-1 and all limbs zero). However, we have a
history of bugs where a function that should produce an official
zero (with s=1), produces a negative zero in some circumstances. So it's
good to check that the bignum functions are robust when passed a negative
zero as input. And for that, we need a way to construct a negative zero
from test case arguments.
There are checks that functions don't produce negative zeros as output in
the test suite. Skip those checks if there's a negative zero input: we
don't want functions to _create_ negative zeros, but we don't mind if
they _propagate_ negative zeros.

This exposes a bug in mbedtls_mpi_add_mpi() and mbedtls_mpi_sub_mpi() which
will be fixed in a subsequent commit.

Although our build scripts support that, it's annoying, because it makes
"test_suite_XXX" ambiguous between "all the data for
test_suite_XXX.function" and "just test_suite_XXX.data".

It just got renamed, and it's also not the most canonical example since it's
a somewhat deprecated interface in the development branch. Make a different
module the example.

Align the name of the bignum test suite with the source module (which was
renamed from mpi.c to bignum.c in the PolarSSL 1.x days). This also brings
it into line with the test suites for the low-level bignum interfaces.

Looking for executables causes problems with leftover compiled test
suites from other branches when we forget to run make clean before
switching branches. Using the .data files is more robust as most of them
are tracked, so will be removed when switching branches.

For the benefit of auto-formatting tools, move from the '$placeholder'
templating syntax to a new syntax of the form:
__MBEDTLS_TEST_TEMPLATE__PLACEHOLDER
This change allows the test code template to be almost entirely valid C.

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.

Most of the tests (including those using endpoint_init functions) parse
certificates that require MBEDTLS_SHA256_C to be present.

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.
