…kedContract (#1783)

* Add support for Vyper cbor auxdata in bytecode-utils and consequently in VyperCheckedContract

* handle vyper incorrect semver versions, support auxdata position also for versions < 0.3.10

* Refactor Solidity and Vyper contract handling to improve auxdata extraction

- Changed `auxdataStyle` in `SolidityCheckedContract` to be a static readonly property.
- Updated bytecode decoding in both `SolidityCheckedContract` and `VyperCheckedContract` to use the static `auxdataStyle`.
- Simplified `generateCborAuxdataPositions` method in `VyperCheckedContract` by introducing a helper function for auxdata position generation.
- Added comments to clarify the use of `AuxdataStyle.SOLIDITY` for bytecode decoding in `ChainMonitor` and session state handlers.
- Ensured that `generateCborAuxdataPositions` is called when necessary in `AbstractDatabaseService` to maintain data integrity.

* add comment to explain `generateCborAuxdataPositions` return conditions

* Refactor bytecode decoding to enhance auxdata handling for Vyper versions. Updated the `decode` function to support various auxdata styles, including specific handling for Vyper versions < 0.3.10 and < 0.3.5. Improved error messages for missing auxdata in bytecode. Updated tests to reflect changes in auxdata style usage.

* Refactor bytecode decoding to replace `compiler` with `vyperVersion` in Vyper-related types and tests.
