accounts/abi/bind/v2: add separate BoundContract struct for v2. Previously, it was unintuitive to instantiate a BoundContract instance which contained member methods used by V1 bindings, while the corresponding methods for v2 functionality were implemented as non-member methods. The new v2 BoundContract instance only exposes member methods that are required by the V2 contract interaction utility methods.
