Add a platform function mbedtls_setbuf(), defaulting to setbuf().
The intent is to allow disabling stdio buffering when reading or writing
files with sensitive data, because this exposes the sensitive data to a
subsequent memory disclosure vulnerability.

component_test_cmake_out_of_source was running the ssl-opt.sh test case
"Fallback SCSV: beginning of list", but this test case was removed in Mbed
TLS 3.0, so ssl-opt.sh was running nothing, which is not an effective test.
In 2.x, the test case was chosen because it uses an additional auxiliary
program tests/scripts/tcp_client.pl. This auxiliary program is no longer
used. So instead, run at least one test case that's sure to exist.

`PSA_ALG_AEAD_WITH_SHORTENED_TAG(aead_alg, len) == aead_alg` when
`len == PSA_AEAD_TAG_LENGTH(aead_alg)`. So skip this case when testing
the printing of constants.
This fixes one test case due to the way arguments of
`PSA_ALG_AEAD_WITH_SHORTENED_TAG` are enumerated (all algorithms are tested
for a value of `len` which isn't problematic, and all values of `len` are
tested for one algorithm).

There's nothing wrong with ECC keys on Brainpool curves,
but operations with them are very slow. So we only exercise them
with a single algorithm, not with all possible hashes. We do
exercise other curves with all algorithms so test coverage is
perfectly adequate like this.

RSA-OAEP requires the key to be larger than a function of the hash size.
Ideally such combinations would be detected as a key/algorithm
incompatibility. However key/algorithm compatibility is currently tested
between the key type and the algorithm without considering the key size, and
this is inconvenient to change. So as a workaround, dispense
OAEP-with-too-small-hash from exercising, without including it in the
automatic operation-failure test generation.

In key read tests, add usage flags that are suitable for the key type and
algorithm. This way, the call to exercise_key() in the test not only checks
that exporting the key is possible, but also that operations on the key are
possible.
This triggers a number of failures in edge cases where the generator
generates combinations that are not valid, which will be fixed in subsequent
commits.

When generating storage format tests, pass usage flags around as a list, and
format them as the last thing.
In Storagekey(), simplify the addition of implicit usage flags: this no
longer requires parsing.
The output is unchanged.

In the generated storage format test cases, cover all supported
algorithms for each key type. This is a step towards exercising
the key with all the algorithms it supports; a subsequent commit
will generate a policy that permits the specified algorithms.

`curves.pl` (invoked by `all.sh test_depends_curves`, and
`all.sh test_depends_curves_psa`) currently runs two series of tests:
* For each curve, test with only that curve enabled.
* For each curve, test with all curves but that one.
Originally this script was introduced to validate test dependencies, and for
that all-but-one gives better results because it handles test cases that
require multiple curves. Then we extended the script to also test with a
single curve, which matches many real-world setups and catches some product
bugs. Single-curve testing also validates test dependencies in a more
limited way.
Remove all-but-one curve testing, because it doesn't add much to the test
coverage. Mainly, this means that we now won't detect if a test case
declares two curve dependencies but actually also depends on a third. This
is an acceptable loss.
The trigger for removing all-but-one curve testing is that this will make
the job take only about half as long, and the length of the job was a bit of
a problem. Resolves#5729.

component_test_CID_no_debug was added specifically to be a non-regression
test for https://github.com/Mbed-TLS/mbedtls/issues/3998. Running compat.sh
in the newly introduced config-ccm-psk-dtls1_2.h is also a non-regression
test for that bug. Therefore component_test_CID_no_debug is redundant for
its primary purpose.
Of course every configuration is different, but the additional coverage from
component_test_CID_no_debug is minimal, unlike config-ccm-psk-dtls1_2.h
which is a plausible real-world configuration.
In mbedtls-2.28, component_test_CID_no_debug was never added, and running
the unit tests in that configuration does not trigger the #3998 bug, only
compat.sh does. So, rather than backport component_test_CID_no_debug to
2.28.2, I am removing it from 3.2.

mbedtls/mbedtls_config.h (formerly mbedtls/config.h) used to be included
directly in many places, so we wanted to test that all of these places
allowed the MBEDTLS_CONFIG_FILE override. Now mbedtls/mbedtls_config.h is
only included via build_info.h, so this is not relevant anymore.
It is no longer particularly useful to test MBEDTLS_CONFIG_FILE with the
full config, but it isn't harmful either, so keep it that way.
