refactor: refactor rendering scopes and command encoding

- update default required features to include `target_os = "linux"`
- update mask scope to be of type `&mut commandencoder` instead of `encode`
- update `mask_scope` in `renderer` for `context_scope` in different parts of the code
- update `begin_render_pass` scope for `mask_scope` and `content_scope` to have `renderpassdescriptor` parameters
