feat(android): Add lights and lightColor to PushNotificationChannel

[jcesarmobile]

Add lights and lightColor properties to PushNotificationChannel, so can be used on createChannel and returned by listChannels.

This allows to enable led light for push notifications and configure it's color (if the device supports it)

Also make description and sound optional since the native code had default values for when they are not provided.

closes #2547

is it possible to add Large icon configuration as well for both Push Notification and Local Notification?

whilst you can turn the lights on, the colour cannot be configured. Tested on a note8 which has the ability to change the colour of the lights.
