Similarly to what has been done for the init function, also
the abort function should return a state in case the caller
needs to implement some error recovery procedure, or even
just for debugging reasons.

SHA-256 init functions should return the status of the init
instead of being void. This would allow the callers to implement
proper error recovery, otherwise on error the SHA-256 operation
will enter an undefined behaviour.

This patch refactor the RSA operations done by the signature verification
module and by the encrypted images decryption module. Previous solution is
tightly coupled with Mbed TLS, while this patch provides an abstraction of
the RSA functionalities in a dedicated crypto abstraction header, crypto/rsa.h
that supports both Mbed TLS APIs and PSA Crypto APIs. In case of PSA Crypto,
the verification scheme is directly provided by the crypto backend hence it
simplifies the operations done in the image verification module.

Fix usage of zcbor_new_encode_state API, to correctly pass the payload
length. The previous usage was passing a pointer to the end of the
payload, which resulted in the ZCBOR structure being initialized with
an invalid `payload_end` field. On some platforms, this breaks MCUBoot
serial recovery, as the ZCBOR structures required to send response data
are invalid and can no longer be populated with response data.

The IMAGE_TLV_ECDSA256 TLV has been put out of use by
commit 63d2346da4.
This commit reverts this part of that patch and at the
same time it extends the usage of this TLV to cover all types
of curves (replacing the newly introduced 0x25 TLV type)
while retaining its value (0x22) for backward compatibility.
Rename IMAGE_TLV_ECDSA256 to IMAGE_TLV_ECDSA_SIG.
