Remove fontCachePath from settings model

[jakubjo]

The fontCachePath property is being removed from the Settings model.

The default directory where web fonts are cached is Craft::$app->path->getRuntimePath() . '/spfonts', which usually evaluates to storage/runtime/spfonts.

If you want to customize the directory you can do so by listening to the ResolveFontCachePathEvent event.
Set your custom path by setting the path property one the instance of ResolveFontCachePathEvent:

use alps\sharepreviews\events\ResolveFontCachePathEvent;
use alps\sharepreviews\services\FileHandler;
use yii\base\Event;

Event::on(FileHandler::class, FileHandler::EVENT_RESOLVE_FONT_CACHE_PATH, function(ResolveFontCachePathEvent $event) {
    $event->path = 'cache/fonts';
});

Thanks @andypullen for bringing this to my attention.
