* [jquery] Fix return type of `JQuery.map`.
The type parameter of the JQuery object returned from `JQuery.map` depends on the return values of the callback. Previously, the type parameter was based on the object it was called on.
This fix requires dropping constraints on `JQuery`, `JQueryStatic`, `EventHandler`, and `EventHandlerBase` as `JQuery.map` may return `JQuery` objects that contain non-`Node` values.
* [jquery] Fix return type of `JQueryStatic.map`.
* [jquery] Declare type for `this` in callback for `JQueryStatic.map`.
* [jquery] Fix return type for `JQueryStatic()`.
* [bootstrap] Match change to `JQuery` interface.
* [flight] Fix test failure due to change in `@types/jquery`.
* [materialize-css] Fix test failure due to change in `@types/jquery`.
* [select2] Match changes to `@types/jquery` interfaces.
* [jquery] Fix error due to breaking change in TypeScript lib declarations.
