And use it in the non-PSA version of mbedtls_pk_sign_ext()
to bypass checks that didn't succeed when used by TLS 1.3.
That is because in the failing scenarios the padding of
the RSA context is not set to PKCS_V21.
See the discussion on PR #7930 for more details.

Add configuration to enforce minimum size when
generating a RSA key, it's default value is 1024
bits since this the minimum secure value currently
but it can be any value greater than or equal 128
bits. Tests were modifed to accommodate for this
change.

We just want to check if this hash is available, and the check is
present in builds both with PSA and without it. The function we were
using is only present in builds with PSA, so it wasn't appropriate.

As usual, just a search-and-replace plus:
1. Removing things from hash_info.[ch]
2. Adding new auto-enable MD_LIGHT in build-info.h
3. Including md_psa.h where needed

Now the MD macro also accounts for PSA-only hashes.
Just a search-and-replace, plus manually removing the definition in
hash_info.h.

Mostly a search and replace with just two manual changes:
1. Now PK and TLS need MD light, so auto-enable it.
2. Remove the old function in hash_info.[ch]

Same note as previous commit regarding guards.
Note that we could auto-enable MD_LIGHT only when SELF_TEST is defined,
and even only when SHA1_C is defined too, but somewhere down the line
we'll want to auto-enable it for the sake of other RSA function (not in
selftest and could use any hash), so there's little point in optimizing
the temporary condition, let's use the simple one upfront.

Move all error translation utilities to psa_util.c.
Introduce macros and functions to avoid having
a local copy of the error translating function in
each place.
Identify overlapping errors and introduce a
generic function.
Provide a single macro for all error translations
(unless one file needs a couple of different ones).

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')
```

Test coverage not there yet, as the entire test_suite_pkcs1_v21 is
skipped so far - dependencies to be adjusted in a future commit.
