accounts/abi/abigen: add GetABI() method to abigen v2 generated bindings

Adds a GetABI() accessor to the generated contract struct so callers in
other packages can retrieve the parsed abi.ABI without having to call
ParseABI() themselves. Previously the abi field was unexported and
inaccessible outside the generated package, forcing users to re-parse
the ABI manually.

Fixes #34705
