d4fc5d9d1c psa_util: allow larger raw buffers in mbedtls_ecdsa_raw_to_der() 
The only real contraint on the raw buffer is that it is large
enough to contain 2 coordinates. Larger buffers are therefore
allowed and the extra data will simply be ignored.

Note = trying to impose a strict sizing on the raw buffer causes
       several failures in test suites. This suggests that it is
       quite common to use larger buffer to store raw signatures.

bec1d842ac psa_util: convert_der_to_raw_single_int() accepts also all zero integers 
These values are not mathematically valid as signature, but as
for what it concerns with ECDSA conversion functions, 0 values
in DER format should be translated to 0 values in raw format.

954ef4bbd5 psa_util: improve convert_raw_to_der_single_int() 
Allow the function to support DER buffers than what it is nominally
required by the provided coordinates. In other words let's ignore
padding zeros in the raw number.
