crypto.ecdsa: migrate core routines for signing (and verifying)

[blackshirt]

This PR is the main part of the migration efforts to the crypto.ecdsa module to support for the high level unobsoleted API. The old OpenSSL 1.1.1. series has reached its End of Life (EOL). As such it will no longer receive publicly available security fixes, see eol-of-ossl.1.1.1 for more detail, so, maybe better to just upgrade your openssl to the 3.x series.

In this current PR, the main concerns was adding support to .sign() and .verify() routines to support the new api. Its done by using some changes to the internal detail of the current one, ie, in the form:

• Adds support to use a new high level opaque into .sign() and .verify() methods.
• Renames internal .sign_message into .sign_digest to reflect underlying its wrapped. Its sign the digest internally.
• Adds some helpers to cooperate with the rest. Some helpers are just redundant with the old one, because we supporting two opaque here, but, its can be removed (cleaned) on later pr.
• Adds some C required declarations.
• Some bits of cleans up

Thats its. thanks

Okey ..i saw v2 related errors i cant reproduce.. is this related with the ci runners?

I only see crypto/ecdsa test failures in the last run.
