haptic: Feature to disable it when usb port is not configured or suspended. (#12692)

Browse source 
This also add support for specifying a LED pin to indicate haptic status,
and also adds support for a haptic-enable pin, which is useful to turn off
the boost converter on the solenoid driver.

The following `config.h` settings are available for all types of haptic feedback:
| Settings | Default | Description |
|--------------------------------------|---------------|---------------------------------------------------------------------------------------------------------------|
|`HAPTIC_ENABLE_PIN` | *Not defined* |Configures a pin to enable a boost converter for some haptic solution, often used with solenoid drivers. |
|`HAPTIC_ENABLE_PIN_ACTIVE_LOW` | *Not defined* |If defined then the haptic enable pin is active-low. |
|`HAPTIC_ENABLE_STATUS_LED` | *Not defined* |Configures a pin to reflect the current enabled/disabled status of haptic feedback. |
|`HAPTIC_ENABLE_STATUS_LED_ACTIVE_LOW` | *Not defined* |If defined then the haptic status led will be active-low. |
|`HAPTIC_OFF_IN_LOW_POWER` | `0` |If set to `1`, haptic feedback is disabled before the device is configured, and while the device is suspended. |
