feat: [SIW-1844] Add trustmark generation functions

[mastro993]

List of Changes

• Added getCredentialTrustmarkJwt function, which returns the credential's trustmark JWT
• Updated the example app with the screens, store and functions to test the new trustmark functionality

Motivation and Context

This approach addresses vulnerabilities in the previous static QR code implementation.
This new TrustMark implementation binds the QR code to the specific credential being verified, preventing QR code swapping and ensuring unique, tamper-proof authentication. It uses a signed JWT with a short validity period for enhanced security.

The trustmark JWT can be obtained using the following function, exported from Credential.Trustmark:

function getCredentialTrustmark({
  walletInstanceAttestation: string,
  wiaCryptoContext: CryptoContext,
  credentialType: string,
  docNumber?: string,
  expirationTime?: number | string
}): Promise<{
  jwt: string,
  expirationTime: number
}>

How Has This Been Tested?

Tested the Trustmark generation using the example app
