Replace internal hook configuration with HookimplConfiguration

- Update HookimplMarker to store HookimplConfiguration objects directly
- introduce PluginManager._parse_hookimplv to do most of the hook parsing
- Convert parse_hookimpl_opts to compatibility shim that returns None (allow pytest to work)
- Update test to use direct attribute access instead of dict .get() method
- Eliminate redundant dict-to-config conversions in plugin registration
- Remove HookImpl.opts deprecated attribute
- Update benchmark tests to use hookimpl.get_hookconfig() directly
- Eliminates internal HookimplOpts conversions while preserving public API
- Add HookimplMarker.get_hookconfig() method that returns HookimplConfiguration directly
- Update test files to use new method instead of accessing dynamic attributes
- Fix mypy type errors in test_multicall.py and test_hookcaller.py
