feat: allow webauthn info to be passed in wallet creation

[weldon-bitgo]

Ticket: WP-8495

Description

This PR allows webauthn information to be passed during wallet creation. Ultimately, this enables passkeys to be added to wallets during wallet creation; otherwise, passkeys must be added to wallets after they have been created. This change will allow us to introduce an optional passkey addition step during the wallet creation process.

Issue Number

WP-8495

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Two new test files are added for this change.
walletsWebauthn.ts contains unit tests for Wallets.generateWallet and tests that:

• webauthnDevices is populated with correct device metadata and PRF-encrypted private key
• both the wallet passphrase and PRF passphrase produce separate encrypt calls
• webauthnDevices is omitted when webauthnInfo is absent or no private key is available

generateWallet.ts contains Express route tests and tests that:

• the happy path passes webauthnInfo through to generateWallet and returns a status code of 200
• requests with missing otpDeviceId, prfSalt, or passphrase each return a status code of 400
