This value should be:
- OK for all EC/FFDH key pairs/public keys;
- OK for all supported public RSA keys;
- OK for RSA key pairs up to 2048 bits;
- FAIL for RSA key pairs above 2048 bits.

Intentionally set MBEDTLS_PSA_STATIC_KEY_SLOT_BUFFER_SIZE slightly
smaller than the maximum RSA key pair size for an RSA key of 4096
bits. Also add a test in test_suite_psa_crypto to verify this
condition.

Instead of checking for "in_use" to be true/false or "key.data"
to be not NULL, simply check that "key.bytes" is 0/not-0.
psa_allocate_buffer_to_slot() will update this value whenever
a new slot is allocated (for the fully static case "allocated"
actually mean "taken").

If MBEDTLS_PSA_STATIC_KEY_SLOTS is set then limit PSA_CRYPTO_MAX_STORAGE_SIZE
to MBEDTLS_PSA_STATIC_KEY_SLOT_BUFFER_SIZE, otherwise keep the previous
PSA_BITS_TO_BYTES(PSA_MAX_KEY_BITS) size.
This commit also removes changes to test_suite_psa_crypto_persistent_key.data
done previously since MBEDTLS_PSA_STATIC_KEY_SLOTS is always up to date
with key buffer size.

Disable all MBEDTLS_xxx symbols (keeping only the relevant ones enabled)
when building the main library.

This commit also fixes related errors in test suites. In all
cases those failures are related to the use of raw keys whose
size cannot be determined a-priori.

This helps reducing heap memory usage and, if heap memory is
not used anywhere else in an embedded device, it also reduces
code footprint since there is no need for heap management code
in this case.
A new build symbol is added for this purpose, named
MBEDTLS_PSA_STATIC_KEY_SLOTS. It's disabled by default so that
normal usage of Mbed TLS library is not affected.

In 4.x the semantics of MBEDTLS_PSA_CRYPTO_C and
MBEDTLS_PSA_CRYPTO_CLIENT are different compared with 3.6.
Where this is a problem, make guards more version-specific so that we
are guarding with MBEDTLS_PSA_CRYPTO_C for 3.6 and
MBEDTLS_PSA_CRYPTO_CLIENT for 4.x, keeping each branch the same as it
was formerly.

Without quotes, when the variable is empty, the shell will see three
tokens: [, -n, ]. After skipping ] as usual, it will see a single token,
so it will consider it not as command, but a string to be tested for "is
it empty", and since "-n" is not empty, the command will return true.
With quotes it see 4 tokens: [, -n, <empty string>, ] and interprets -n
as desired.

Now the output of
grep '^[^ {}#]' tests/scripts/all-*.sh | grep -v '()'
is clean, with the only results being:
- shopt -s extglob which is needing for parsing the rest
- usage message

The only occurrences found by git grep were the definitions and the

Don't interleave defining functions with running some code.
The only exception is calling shopt, which needs to come first as it
affects how the following function definitions are parsed.

This change is not correct for 3.6 and will be reverted. It is only
applied as a temporary measure to avoid conflicts while cherry-pick
changes from development.
