refactor!: always use Do for callbacks

[vbreuss]

This PR refactors the callback API for properties and indexers by introducing a mandatory Do method, replacing the previous pattern where OnGet and OnSet directly accepted callbacks. This is a breaking change that improves API clarity and consistency.

Key Changes:

• Changed OnGet and OnSet from methods accepting callbacks to properties returning setup interfaces
• Introduced IPropertyGetterSetup/IPropertySetterSetup and IIndexerGetterSetup/IIndexerSetterSetup interfaces with Do methods
• Updated all test files to use the new OnGet.Do(...) and OnSet.Do(...) syntax

• Fixes Always use Do for callbacks #284
