refactor(mobile): build context extensions (#4923)

* refactor: move all extensions to separate package * refactor(mobile): add BuildContext extension * refactor(mobile): use theme getters from context * refactor(mobile): use media query size from context * refactor(mobile): use auto router methods from context * refactor(mobile): use navigator methods from context --------- Co-authored-by: shalong-tanwen <139912620+shalong-tanwen@users.noreply.github.com>
