feat(mbedtls-psa): mbedTLS PSA Crypto with ECDSA
The ECDSA algorithm signature verification in the PSA differs
from the RSA algorithm in its handling of data formats. In the
case of RSA, an encoded ASN1.0 buffer is passed to the PSA API,
which then decodes the buffer. However, for ECDSA, the PSA API
expects a raw format.
To accomodate this requirement, introduce several static APIs
that allows to retrieve -
1. ECDSA public key data pointer along with its size, and also,
the ECC family in PSA format from the public key.
2. R and S pair of the ECDSA signature along with its size
