[AnkushinDaniil]

Review and merge after #2407

This pull request partially reverts #2229

Changes to MockVM and ThrottledVM:

• Modified the Call and Execute methods in MockVM to accept an additional boolean parameter useBlobData. (mocks/mock_vm.go) [1] [2]
• Updated ThrottledVM to include the useBlobData parameter in its Call and Execute methods. (node/throttled_vm.go) [1] [2]

Changes to RPC Handlers:

• Introduced new methods BlockWithTxHashesV0_6 and BlockWithTxsV0_6 to handle version 0.6 specific responses. (rpc/block.go) [1] [2]
• Added a new type FeeEstimateV0_6 and corresponding conversion functions to support fee estimation for version 0.6. (rpc/estimate_fee.go) [1] [2]
• Implemented EstimateFeeV0_6 and EstimateMessageFeeV0_6 methods to handle fee estimation for version 0.6. (rpc/estimate_fee.go) [1] [2]

Additional Changes:

• Updated the New function in node/node.go to register methods for both version 0.6 and 0.7, and adjusted the metrics accordingly. (node/node.go) [1] [2]
• Added tests for the new version 0.6 methods to ensure they work correctly. (rpc/block_test.go, rpc/estimate_fee_test.go) [1] [2] [3]

These changes ensure that the API can handle both version 0.6 and 0.7 requests, providing backward compatibility and supporting new features.
