For each curve defined MBEDTLS_ECP_DP_xxx_ENABLED, we have a
corrsponding PSA config define PSA_WANT_ECC_xxx. Along with that is a
value MBEDTLS_PSA_ACCEL_ECC_xxx which can be used to allow HW
acceleration of that particular curve.
If the PSA config requests an unaccelerated curve, the corresponding
MBEDTLS_PSA_BUILTIN_ECC_xxx will also be defined.
This commit defines these for all curves currently defined, with the
defines working in either direction, depending on whether
MBEDTLS_PSA_CRYPTO_CONFIG is defined.

MinGW and older windows compilers cannot cope with %zu or %lld (there is
a workaround for MinGW, but it involves linking more code, there is no
workaround for Windows compilers prior to 2013). Attempt to work around
this by defining printf specifiers for size_t per platform for the
compilers that cannot use the C99 specifiers.

This was a false positive caused by the compiler seeing the %08lx
specifiers and judging the output on that, rather than the numbers being
fed in. Given these are going to be maximum 32 bit numbers, then better
to use %08x, which keeps -Wformat-truncation=2 happy as well.

Fixes for printf format specifiers, where they have been flagged as
invalid sizes by coverity, and new build flags to enable catching these
errors when building using CMake. Note that this patch uses %zu, which
requires C99 or later.

Printf could potentially produce 2 64 bit numbers here when there is
only space for one, thus causing a buffer overflow. This was caught by
the new warning flags.

We were not getting any warnings on printf format errors, as we do not
explicitly use printf anywhere in the code. Thankfully there is a way
to mark a function as having printf behaviour so that its inputs can be
checked in the same way as printf would be.

Add extra printf warning flags into the cmake build, only adding those
that are supported by each version of the compiler

Clang 11 has stopped using the old comment system to mark deliberate
fallthrough, and now demands marking of such with
__attribute(fallthrough). Given not every compiler supports such
attributes and these are the only two deliberate fallthrough cases in
the project at the minute, take the easy route and just remove the
fallthrough.

Test hash algorithm functions when called through a transparent
driver in all.sh test_psa_crypto_config_basic and
test_psa_crypto_drivers components.

Apply the right define guards for the right purpose. The 'core' hash
driver is included if any hash algorithm is either to be tested through
the test driver, or if it is requested by a user and not accelerated
(i.e. 'fallback'/'software' driver requested for the algorithm).

Apparently there's a goal to make the PSA Crypto core free from
dynamic memory allocations. Therefore, all driver context structures
need to be known at compile time in order for the core to know their
final size.
This change defines & implements for hashing operations how the context
structures get defined.

Fix places where Doxygen documentation uses \p to refer to a parameter
name and where the name used did not match the actual parameter name.
I used the following script to detect problematic cases:
```
perl -w -ne 'if (eof) { $. = 0; } if (m!^/\*\*!) { $in_doc = 1; %param = (); %p = (); } if (m!\*/!) { foreach $name (keys %p) { if (!$param{$name}) { foreach $line (@{$p{$name}}) { print "$ARGV:$line: $name\n" } } } $in_doc = 0; } if ($in_doc) { if (/\\param(?: *\[[^\[\]]*\])? +(\w+)/) { $param{$1} = 1; } foreach (/\\p +\*?(\w+)/) { push @{$p{$1}}, $.; } }' include/psa/*.h
```
This commits fixes all the remaining occurrences under include/psa,
which were just trivial name mismatches.

In Doxygen documentation, use \c rather than \p when discussing
something that isn't a parameter of the current macro or function.
Where needed, explain what the thing is.
