Fixed the Joldurbraan Boss fight and added several optimization to improve performance.

• Joldurbraan boss fight should now be completable in all cases. The fight is back to sequenced/gated mechanic with ice walls separating each enemy as originally designed and fix issues with collision/navigation to correct enemy movement.
• Added an "Input Queue enabled/disabled" option has been added to the Game section of Settings, allowing players to select and use the previous input handling mechanics.
• Corrected false positive cases when saving Settings.
• Optimization to the iteration and searches of items in inventory
• Reduce hitching and total time dungeon floors take to load by adding cache-friendly lookups to spawn selection.
• Optimization for Shadow casting lights by disabling shadows when Shadow quality is lower than 3 (High)
• Disabled distance field lighting for small objects that will not contribute to this lighting, reducing the GPU cost on lower performing devices.
