76336c3e4d Enforce minimum key size when generating RSA key size
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.

28f504e892 Use PSA-neutral function for availability check
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.

b33ef74d44 Use MD_LIGHT, not sha1.h, in RSA selftest
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.

945b23c46f Include platform.h unconditionally: automatic part
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"')

4772884133 New internal module for managing hash information
Using static inline functions is bad for code size; the function from
md_internal.h was already used from 3 different C files, so already was
copied at least 3 times in the library, and this would only get worse
over time.

Use actual functions, and also share the actual data between them.

Provide a consistent set of operations. Conversion to/from
human-readable string was omitted for now but could be added later if
needed.

In the future, this can be used to replace other similar (inline)
functions that are currently scattered, including (but perhaps not
limited to):
- mbedtls_psa_translate_md() from psa_util.h
- mbedtls_md_info_from_psa() (indirectly) from psa_crypto_hash.h
- get_md_alg_from_psa() from psa_crypto_rsa.c
