A core MPI must have at least 1 limb. We can no longer test with 0 limbs,
and we don't need to anyway, so don't try.

This way static analyzers have a chance of knowing we don't expect the
bignum functions to support empty inputs. As things are, Coverity keeps
complaining about it.

Instead of corrupting the public key part of the message,
corrupt the proof part. A proof is conceptually similar to a signature,
and changing anything in it should make it invalid with
a high probability.
Also, instead of shifting data, perform a bitflip.

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.

Legacy Bignum is excluded as it doesn't get regular extensions like new
ones.
Each slot uses comments of their respective filetype. Since .data files
don't have a syntax for comments, dummy test cases are used. (These test
cases will never be executed and no noise will be added to tests.)

I ran into a sequence where the assertion `stats[8] > 0` failed for the
range 1..272 with 100 iterations.

Turn mpi_fill_random_internal() into mbedtls_mpi_core_fill_random(). It
had basically the right code except for how X is passed to the function.
Write unit tests.

* component_test_tls13_with_padding: just explicitly sets some options that
are identical with full.
* component_test_tls13_with_ecp_restartable: redundant since TLS 1.3 doesn't
have any support for restartable ECC.
* component_test_tls13_with_everest: not useful since TLS 1.3 doesn't call
ECDH directly, it just relies on the PSA abstraction.

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.

MBEDTLS_TEST_HOOKS is not supposed to change the behavior of the library, so
it's generally good to have it on in functional tests.

This patch addresses review comments with regards to style of

It also removes a test check which was triggering a use-after-free.
