Switch disabled track and thumb color

Is your feature request related to a problem? Please describe.
No.

Describe a solution you'd like
I saw that the disabled colors are hard-coded so I would only change them with variables passed from props. Eg. I would add two more props disabledTrackColor and disabledThumbColor. I feel like that styling should be adjustable, because not everyone is happy with those colors.

Describe alternatives you've considered

Additional context
Eg. I have a switch with red track and white thumb and I would like it to have some light red color for track and some light grey color for thumb when disabled, instead of those that are hard-coded.

@reck753 This PR resolves the above issue in a different way.
You can change trackColor and thumbColor conditionally according to disabled condition.
I think, we can't introduce new props as react-native also doesn't provide disabledTrackColor and disabledThumbColor.

Hi, @makkarMeenu!
Thanks for the PR! This would be a good enough solution for me.
