This adds two new event actions under the Time category that allow developers to change the game's maximum and minimum FPS during runtime. These values are applied directly to the RuntimeGame instance and affect the rendering loop's frame rate capping behavior. Note: No validation is currently performed. Negative values or setting minFPS greater than maxFPS may lead to undefined behavior or visual issues. Future improvements could include IDE-level validation or runtime warnings.

Summary
This PR adds two new actions under Game scene (Events) in GDevelop that allow developers to dynamically configure the game's maximum and minimum frames per second (FPS) during runtime.
These settings are useful for:
Reducing FPS during non-interactive scenes (e.g., cutscenes).
Exposing FPS settings in a game’s graphics or performance menu.
Implementation Details
Actions are declared in TimeExtension.cpp using .AddAction(...).
Mapped to new JS runtime functions:
FPS values are applied to RuntimeGame._maxFPS and _minFPS, which affect the main game loop behavior.
