Implementation of pairings-signatures-library

[mxtartaglia-sl]

Overview

Following https://github.com/hashgraph/hedera-services/blob/8354afb91d643d8e06f5ef67d2914f032b95a5d7/platform-sdk/docs/proposals/TSS-Library/TSS-Library.md
Sections:

• Swirlds Crypto Pairings Signature Library

Create the components that enable users to create EC Private/Public Keys and Signatures. The operation of signing must be implemented in this ticket. Encryption will be done separately. Protobuf is required for passing data to arkworks. Data should not be stored in the state that depends on how arkworks does serialization, so the signature data from arkworks must be defined in protobuf.

This ticket is complete when we can create public/private key pairs, sign data with the private key, and verify signatures with the public key.

1. Create the method that invokes the operations for creating the public/private key pairs
2. Create the method that signs a byte array
3. Create the method that verifies a signature
4. Convert all data in the prior 3 steps that use arkworks serialization that must also be stored in state to protobuf

This task depends on:

• Implementation of parings-api-impl using JNI, arkworks, and alt-bn128 #13630
• Organize Hedera-Cryptography Repository and create necessary gradle modules and plugins #13324
• hedera-cryptography Repository CI/CD #14100
