feat: add saml request to link to sessions (#9001)

# Which Problems Are Solved It is currently not possible to use SAML with the Session API. # How the Problems Are Solved Add SAML service, to get and resolve SAML requests. Add SAML session and SAML request aggregate, which can be linked to the Session to get back a SAMLResponse from the API directly. # Additional Changes Update of dependency zitadel/saml to provide all functionality for handling of SAML requests and responses. # Additional Context Closes #6053 --------- Co-authored-by: Livio Spring <livio.a@gmail.com>
