Certificates relevant methods should be moved from `utils.ts` to `certificates.ts`

[sitetester]

Description

In https://github.com/LiskHQ/lisk-sdk/pull/7416, we added certificates.ts with TODO: Now that we have certificates.ts, these methods could be moved there (checkCertificateTimestamp, checkCertificateValidity, checkValidatorsHashWithCertificate, checkValidCertificateLiveness, isCertificateEmpty, verifyCertificateSignature)

Motivation

• utils.ts is huge, now that we have a separate file, we should move all certificates related methods in this new file.

Additional Information

• framework/src/modules/interoperability/utils.ts
• framework/src/modules/interoperability/certificates.ts
• https://github.com/LiskHQ/lisk-sdk/pull/7416
