Slider ticks enhancements

[Aleksandyr]

Description

Slider improvements:

• Remove isCountinuous input.
• Remove Hummer module
• Remove ngZone dependency injection.
• Remove all unused imports
• All Enum values to pascal case.
• Update stepDistance only when you change the step input. (stepChange evt)

For the last requirement, we will need to implement resizeObserver because the calculation depends on the slider width.
