Library Design Refactoring and Code Re-Organization

[opencrypto]

The refactoring of the Crypto layer is long due. This pull request covers a comprehensive refactoring of the library to allow for better code management and easier use of the library:

CRYPTO Level Refactoring:

• Add a new CRYPTO layer to correctly handle key pairs and low-level crypto operations
• Refactor the HSM layer to provide HSM management, KEY storage, and crypto functions
• Remove support for network in/out functionalities from the HSM layer
• Integrate Composite Crypto from external providers
• Remove old experimental code

X509 Layer Refactoring (low level):

• Add a new X509 abstraction layer to correctly handle X509 structures and functions
• Provide a generalized layer to create, destroy, and manage X509 data structures
• Define layer's boundaries (X509 vs. PKIX)

PKIX Layer Addition (higher level):

• Add a new PKIX abstraction layer to correctly handle PKIX protocols
• Move all PKIX functionalities to this layer

X9F Layer Addition (protocol layer):

• Add support for ISARA Catalyst extensions (X509 layer)
• Add support for ISARA Catalyst Certificate Signing (X509 layer)
• Add support for X9 CKS Hello Extension (X509 layer)
• Add support for X9 MFA CertificateVerify extension (X509 layer)

TLS Layer Refactoring:

• Simplify and extend support for TLS
• Move TLS to a new abstraction layer from the net utils
• Add support for QTLS when using ISARA Catal (TLS layer)
