Evict frames for hidden webviews

Bug Description

When a webview is hidden we hold on to the frontbuffer until it is made visible again. Instead of doing this, we should consider evicting all buffers for hidden views in order to free resources. A tradeoff of this would be small delay when making a hidden view visible again.

On Android, Chrome evicts frames for all hidden views. On destkop, it doesn't evict all of them but does cap the number based on available memory
