ButtonSettings: Rework buttons/keyboard backlight control enablement
Let's end once and for all with the nonsense of using floats
config_{button,keyboard}BrightnessSettingDefaultFloat to enable
button and keyboard brightness control, respectively.
Instead, just move over to the recently introduced integers
config_deviceSupports{Button,Keyboard}BrightnessControl.
This avoids people with devices with hardware keys having to
overlay config_{button,keyboard}BrightnessSettingDefaultFloat to
a value of 0.0 just to disable the unsupported features.
