[XCX] Create new XCX

This update introduces enhancements to the graphical settings of Xenoblade Chronicles X by modifying the game's boot configuration file. The following adjustable parameters have been identified to produce noticeable visual differences:

* sRGB Mode Toggle: Enables or disables sRGB color mode, affecting color accuracy and vibrancy.​

* Anti-Aliasing Toggle: Turns anti-aliasing on or off, impacting the smoothness of object edges and overall image clarity.​

* Bloom Effect Toggle: Allows the activation or deactivation of the bloom effect, influencing the intensity of light glow and scene brightness.​

* Cloud Height Minimum: Adjusts the minimum altitude at which clouds appear, altering the cloud coverage and atmospheric depth.​

* Cloud Height Maximum: Sets the maximum altitude for cloud rendering, affecting the vertical span of cloud formations in the sky.
