feat: support for Cosmos Ecosystem based wallet addresses in Verification Methods + verification Method Type condition rearrangements

[arnabghose997]

• Users can add their Cosmos based bech32 wallet addresses in their DID Documents. The format for blockchainAccountId is cosmos:<chain-id>:<bech-32 encoded wallet address>. Currently, the support is limited to the following chains:

  • Mainnet Chains:
    • Cosmos Hub (cosmoshub-4)
    • Osmosis (osmosis-1)
    • Akash Network (akashnet-2)
    • Persistence (core-1)
    • Crypto.org (crypto-org-chain-mainnet-1)
  • Testnet Chains
    • Cosmos Hub (theta-testnet-001)
    • Osmosis (osmo-test-4)
    • Stargaze (elgafar-1)
    • Persistence (test-core-1)
    • Hypersign Testnet (jagrat)

• The branching of Verification Method Types is done based on the following relationships between itself and attributes such as blockchainAccountId and publicKeyMultibase

↓ VM Type / VM Attributes →	publicKeyMultibase	blockchainAccountId	Valid/Invalid ?

• This PR can only be merged after the successful merging of refactor: createDID, deactivateDID, updateDID RPCs #338
