overlay: Settings: Enable multiple vibration strength levels

All production zumapro devices have CS40L2x haptic driver ICs that support
multiple intensities, so expose the Off/Low/Medium/High vibration
strength options like stock.

<!-- The number of vibration intensity levels supported by the device.
Note that this should correspond to the ability to vary the vibration amplitude, with
enough dynamic range to have at least as many distinct intensity levels as defined here.
Supported values are 1, 2, 3. If '1', the settings app will use a toggle for the settings,
otherwise a slider. If '3', the settings app maps intensities directly to the levels
supported by the Vibrator HAL APIs. If '2', then the levels will be mapped to
VIBRATION_INTENSITY_LOW and VIBRATION_INTENSITY_HIGH, which gives the most range for
scaling vibrations. The medium intensity will be skipped.
The default intensity values are configured at
frameworks/base/core/res/res/values/config.xml's config_default[type]VibrationIntensity.
Make sure that each default intensity value is consistent with the supported levels set
here. If this settings supports only 2 levels, for example, then the default intensity
should be either LOW (1) or HIGH (3).
