Weston Ruter 1d0e9badff Script Loader: Guard against exponential recursion during calculation of loading strategy and fetchpriority. ...

This addresses a performance issue in the recursive `WP_Scripts::get_highest_fetchpriority_with_dependents()` and `WP_Scripts::filter_eligible_strategies()` methods for redundant processing of shared dependencies in complex dependency graphs. To fix this, a `$stored_results` param is introduced which is passed by reference; this variable contains a cache of the calculated results for all scripts handles, so that subsequent calls for the same handle can return the cached value instead of re-computing it.
