Stores: Externally tracked state and reactive collections (#4483)

* map signals mutably * boxed signals * remove mutable borrow type from boxed writable * improve map mut example * restore boxed_mut helper * make boxed readable/writable types copy * Move away from the ReadOnlySignal alias in examples * automatically convert Write * Fix some tests * ReadSignal and WriteSignal * move read only signal alias * make maps copy * store prototype * implement derive macro * Handle generics in the derive macro * Make Selector boxable * derive boxed conversion * Get rid of store type * Remove hardcoded type from derive macro * selector -> store * Refactor store implementation * more vec methods * todo mvc store example * Implement Storable for HashMap * fix write * restore sorting logic in todomvc * derive readable and writable * improve todomvc store example * Result store * Option store * collect dead subscribers * fix clippy and formatting * recognize some common foreign types automatically * fix foreign stores in props * slice and array selectors * clean up store example * writable is child owned * box selector * read and write to builtins * re-use the proc macro in the derive macro * Switch to a extension trait based approach * switch to extension traits in the derive macro * transposed method * derive enums * Expose Store::new * remove stores from the prelude * More consistent naming scheme for SelectorScope methods * document hashmap methods * document index extension * document option ext * document result ext * document slice extension * document the vec extension * make more methods borrow the store mutably * Move to impls to have higher priority over the builtin write extension traits * fix deadlock * finish stores documentation * Document the store macro * cleanup docs and organization * finish derive docs * fix typo * fix clippy * fix doc tests * fix derive macro with generics * fix clippy * test and fix empty structs * clean up todomvc store example * default to a boxed store writer to make it easier to type when providing to the context api * fix cargo doc * fix clippy in store example * relax generational box lifetime bounds * relax bounds * relax signal bounds * fix compilation * read store * relax bounds on default store impls * fix enum derive * Convert to readsignal and writesignal automatically * simplify type matching logic * add write store * unsized stores * shrink the path vec type * use more concrete types * remove opaque types * remove copy bounds * use lens as generic name everywhere * more consistent borrow semantics * use a concrete type for the signal metadata and mention references in the map docs * improve todomvc store docs * document store derive macro internals * refactor macro * improve selector node documentation * fix clippy * add btreemap * fix doc tests * more option methods * fix doc * fix clippy * add a bunch more result methods * add a bunch of bounds to the iterators * fix clippy * remove option from subscribers * add store macro to generate extension traits * fix store example * fix deadlock * fix docs * fix doc tests * fix clippy * add stores to public api * add store macro, and then update todomvc_store example --------- Co-authored-by: Jonathan Kelley <jkelleyrtp@gmail.com>
