Turns out TLS 1.3 is using the PK layer for signature generation &
verification, and the PK layer is influenced by USE_PSA_CRYPTO.
Also update docs/use-psa-crypto.md accordingly.

Having ECDSA in PSA doesn't help if we're not using PSA from TLS 1.2...
Also, move the definition of PSA_HAVE_FULL_ECDSA outside the
MBEDTLS_PSA_CRYPTO_CONFIG guards so that it is available in all cases.

This is only partial support. Only 'client' and 'server' values are accepted for peer and user.
Remove support for role.

With the introduction of #7047, ssl_tls.c uses
mbedtls_md_error_from_psa. This complicates
the dependencies for compiling in psa_to_md_errors,
since now these should be ifdeffed also by
MBEDTLS_USE_PSA_CRYPTO followed by a series of or'ed
MBEDTLS_HAS_ALG_SHA_XXX_VIA_MD_OR_PSA_BASED_ON_USE_PSA.
Since this mechanism will be removed soon, we can simplify it to
just MBEDTLS_USE_PSA_CRYPTO.

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).

When MBEDTLS_USE_PSA_CRYPTO is enabled, the application must call
psa_crypto_init() before directly or indirectly calling cipher or PK code
that will use PSA under the hood. Document this explicitly for some
functions.
To avoid clutter, this commit only documents the need to call
psa_crypto_init() in common, non-obvious cases: parsing a public key
directly or via X.509, or setting up an SSL context. Functions that are
normally only called after such a function (for example, using an already
constructed PK object), or where the need for PSA is obvious because they
take a key ID as argument, do not need more explicit documentaion.

Explicitly document that when using TLS 1.3, you must initialize PSA crypto
before starting a handshake.

There's no renegotiation in TLS 1.3, so this option should have no effect.
Insist on having it disabled, to avoid the risk of accidentally having
different behavior in TLS 1.3 if the option is enabled (as happened in
https://github.com/Mbed-TLS/mbedtls/issues/6200).
