Expose a function in the IOpenID4VCIClient to enable re-issuance of a credential

[kkmanos]

This function should utilize the OpenID4VCIClientState dependency to check if there is a valid OpenID4VCI session (c_nonce and access_token have not expired) in order to request the issuance of a credential from the issuer (with a different key pair if available) without asking the user to run the authorization flow.

It should also be accompanied by a configurable option in the user's settings menu, allowing users to specify the maximum duration after which reauthentication on the issuer’s authorization server is required, assuming that the OAuth2 token's TTL exceeds the user's specified duration
