Add new GLideN64 settings (#2872)

* Add new GLideN64 settings

- BackgroundsMode: Set the rendering of large background images, like the JFIF backgrounds of Ocarina of Time. Defaults to stripped as it is more accurate. A user may want to change this to one piece mainly for texture pack usage or performance.
- txEnhancedTextureFileStorage: Use HTS cache instead of HTC for enhanced (upscaled) textures. Defaults to HTC.
- txHiresTextureFileStorage: Use HTS cache instead of HTC for HD textures. Textures are streamed from disk, eliminating the need to prefetch the textures at load. Boots the game near instantly and decreases RAM usage. Defaults to HTC.

* Fix BackgroundsMode type
