Implement CtxSettings, use instead of BasicSettings.

[drslebedev]

This PR includes the implementation of CtxSettings, which will replace the existing BasicSettings.

Several tasks need to be addressed following this PR to fully integrate CtxSettings into the codebase:

1. Remove Base Settings Class and BasicSettings. The old BasicSettings and its base class need to be removed to eliminate redundancy and avoid confusion.
2. Eliminate usage of unique_ptr for Block::_settings
3. Update function names to clearly indicate they are associated with CtxSettings, enhancing code readability.
4. Expand Unit Testing. Add comprehensive unit tests specifically targeting CtxSettings .
5. using MatchPredicate = std::function<std::optional<bool>(const pmtv::pmt &, const pmtv::pmt &, std::size_t)>; replace this with the new matcher structure. See here for details.
