Add tinted static UI resource cache

Add tinted static UI resource cache

This change adds a method to the ResourceManager that allows users
to create a tinted version of a static resource. These resources are
cached until the layout changes. In practice, this new functionality
is used to tint the border resource and close button in the tab
switcher.
