Veramo LD suites can only signal support for a single type of Verification Method

Describe the bug

Some suites would work with multiple verification method types.
Examples:

• EcdsaSecp256k1RecoverySignature2020 should be verifiable using EcdsaSecp256k1VerificationKey2019 as well as EcdsaSecp256k1RecoveryMethod2020 since the Secp256k1 public key can also be expressed as the recovery method (blockchainAccountId).
• Ed25519Signature2020 should be verifiable with Ed25519VerificationKey2020 as well as Ed25519VerificationKey2018 since the raw public key material is essentially the same.
• Almost all signature suites should at least attempt to verify against JsonWebKey2020 or Multikey verification methods as long as the public key types match the signature algorithms.
