Refactor: Unify `SysvarCache` (#22843) 

* Unifies SysvarCache filling in the runtime and tests.
Removes new_mock_with_sysvars_and_features()
Removes mock_process_instruction_with_sysvars().
Replaces from_keyed_account() by SysvarCache in vote processor.

* Replaces from_keyed_account() by SysvarCache in BPF loader.
