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.
