Add ViewModeSwitcher control

[BastianLedererIcinga]

resolve #340

The ViewModeSwitcher from icingadb-web and its styles are copied, only type declarations were added/narrowed.

The Controls trait is added with a createViewModeSwitcher() function.

For now the handleControls() function suggested in #340 is implemented, which calls handleRequest() on the ViewModeSwitcher and any other controls added to trackedControls. This allows controllers to choose when handleRequest() runs, so they can load a preferred view mode and subscribe a handler to save
the view mode to preferences beforehand.

I have also given the promise-like idea some thought, and it shouldn't be hard to implement either, the controls that need it could cache that their ON_SUBMIT fired, and override on or provide a separate function to execute handlers registered afterwards immediately. I am unsure which version to prefer, but I think the latter is a bit more confusing, especially when redirects are used in the handlers, callers will still have to pay close attention to when the request is handled.

For the basic functionality of the Controls trait I wrote some tests with claude, I also tried the ViewModeSwitcher together LimitControl that changes the default according to the view-mode in a local controller and it worked fine.

The view mode switcher is no longer aligned to the right as it was before:

Now:

Please fix the alignment and style.

To create a view mode switcher, I used the following code you shared with me, in a controller:

use Controls;
//...
$viewModeSwitcher->on(ViewModeSwitcher::ON_SUBMIT, function (ViewModeSwitcher $switcher): void {
    $this->redirectNow(
        Url::fromRequest()->setParam($switcher->getViewModeParam(), $switcher->getViewMode())
    );
});

$viewMode = $viewModeSwitcher->getViewMode();

$limitControl = new LimitControl(Url::fromRequest());
if ($viewMode === 'minimal') {
    $limitControl->setDefaultLimit(LimitControl::DEFAULT_LIMIT * 2);
}

$this->trackControl($limitControl);
$this->handleControls($this->getServerRequest());

//...
$this->addControl($limitControl);
$this->addControl($viewModeSwitcher);

This seems boilerplate code to write in each controller when we want a ViewModeSwitcher.
At least the adjustment of the default limit for LimitControl in minimal mode could be centralized. Also, the PaginationControl (page numbers) currently isn't adjusted when the user selects minimal mode, the limit switches from 25 to 50, but the number of pages stays the same.
