Lioncash a661025637 core/frontend/applets/web_browser: Make OpenPage() non-const
This is a function that definitely doesn't always have a non-modifying
behavior across all implementations, so this should be made non-const.

This gets rid of the need to mark data members as mutable to work around
the fact mutating data members needs to occur.
