Call the output size macros specifically with asymmetric keys, which
would cause a crash (and thus test fail) should this fix get regressed.

Although checking if the key was symmetric was correct, its easier to
read if we just check the block length is not zero before we use it in a
division.

The previous implementation was hard to understand and could in principle
fail to notice if there was a test case failure and the writing of the
line "Note: $TOTAL_FAIL failures." failed. KISS.

Save the "Test Report Summary" to a file. This can help both CI scripts and
human readers who want the summary after the fact without having to copy the
console output.
Take care to exit with a nonzero status if there is a failure while
generating the test report summary.

The makefiles look for python3 on Unix-like systems where python is often
Python 2. This uses sh code so it doesn't work on Windows. On Windows, the
makefiles just assume that python is Python 3.
The code was incorrectly deciding not to try python3 based on WINDOWS_BUILD,
which indicates that the build is *for* Windows. Switch to checking WINDOWS,
which indicates that the build is *on* Windows.

This file had temporary MBEDTLS_xxx dependencies because it was created when
support for PSA_WANT_xxx was still incomplete. Switch to the PSA_WANT_xxx
dependencies
This fixes the bug that "PSA storage read: AES-GCM+CTR" was never executed
because there was a typo in a dependency.

Previously the check was convoluted. This has been simplified

We previously introduced a safety check ensuring that if a datagram had
already been dropped twice, it would no longer be dropped or delayed
after that.
This missed an edge case: if a datagram is dropped once, it can be
delayed any number of times. Since "delay" is not defined in terms of
time (x seconds) but in terms of ordering with respect to other messages
(will be forwarded after the next message is forwarded), depending on
the RNG results this could result in an endless loop where all messages
are delayed until the next, which is itself delayed, etc. and no message
is ever forwarded.
The probability of this happening n times in a row is (1/d)^n, where d
is the value passed as delay=d, so for delay=5 and n=5 it's around 0.03%
which seems small but we still happened on such an occurrence in real
life:
tests/ssl-opt.sh --seed 1625061502 -f 'DTLS proxy: 3d, min handshake, resumption$'
results (according to debug statements added for the investigation) in
the ClientHello of the second handshake being dropped once then delayed
5 times, after which the client stops re-trying and the test fails for
no interesting reason.
Make sure this doesn't happen again by putting a cap on the number of
times we fail to forward a given datagram immediately.

If PSA_CIPHER_ENCRYPT_OUTPUT_SIZE was called on a non symmetric key,
then a divide by zero could happen, as PSA_CIPHER_BLOCK_LENGTH will
return 0 for such a key, and PSA_ROUND_UP_TO_MULTIPLE will divide by
the block length.

Restore the optimization done in
HEAD^{/Speed up the generation of storage format test cases}
which was lost during refactoring made when adding support for
implicit usage flags.
There are still more than one call to the C compiler, but the extra
calls are only for some key usage test cases.
This is an internal refactoring. This commit does not change the
output of generate_psa_tests.py
