Android: Fix joypad trigger value range 

`Input::joy_axis` converts trigger values to be between 0.0f to 1.0f by default. This is not needed for Android, as values are already within that range, as per Android documentation: https://developer.android.com/reference/android/view/MotionEvent#AXIS_RTRIGGER

This patch prevents this conversion on Android, which caused L2 and R2 triggers to get stuck pressed. https://github.com/godotengine/godot/issues/79263

(cherry picked from commit d413a02079)
