Event: Simulate focus/blur in IE via focusin/focusout (3.x version)
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.
Fixes gh-4856
Fixes gh-4859
Fixes gh-4950
Ref gh-5223
Closes gh-5224
