feat(eidas): Implement eIDAS Crypto Plugin with dependency injection and signing capabilities
- Added ServiceCollectionExtensions for eIDAS crypto providers. - Implemented EidasCryptoProvider for handling eIDAS-compliant signatures. - Created LocalEidasProvider for local signing using PKCS#12 keystores. - Defined SignatureLevel and SignatureFormat enums for eIDAS compliance. - Developed TrustServiceProviderClient for remote signing via TSP. - Added configuration support for eIDAS options in the project file. - Implemented unit tests for SM2 compliance and crypto operations. - Introduced dependency injection extensions for SM software and remote plugins.
