In IE (all versions), `focus` & `blur` handlers are fired asynchronously but `focusin` & `focusout` are run synchronously. In other browsers, all those handlers are fired synchronously. Asynchronous behavior of these handlers in IE caused issues for IE (gh-4856, gh-4859). We now simulate `focus` via `focusin` & `blur` via `focusout` in IE to avoid these issues. This also let us simplify some tests. This commit also simplifies `leverageNative` - with IE now using `focusin` to simulate `focus` and `focusout` to simulate `blur`, we don't have to deal with async events in `leverageNative`. This also fixes broken `focus` triggers after first triggering it on a hidden element - previously, `leverageNative` assumed that the native `focus` handler not firing after calling the native `focus` method meant it would be handled later, asynchronously, which was not the case (gh-4950). To preserve relative `focusin`/`focus` & `focusout`/`blur` event order guaranteed on the 3.x branch, attach a single handler for both events in IE. A side effect of this is that to reduce size the `event/focusin` module no longer exists and it's impossible to disable the `focusin` patch in modern browsers via the jQuery custom build system.
