Enable styles for buttons as well as enable disabling and enabling buttons

[Monir-Shembesh]

Sorry for the hassle of making one pull request to all features, but thought it would make sense.

I am currently working on a project and found out that I need to disable the increment and decrement buttons when the user reaches the max or min values specified.

Therefore, the following was done:

1- add expected props to the typescript interface following a previous name convention used with the icon styles
2- change the style prop on the increment and decrement to be an array
3- spread the upcoming props that are related to the button styles if true other wise just use {}
4- add a disabled prop to the buttons
5- write a condition inside the disabled prop that checks if the max/min reached as well if the user passed the disablers props disableIncButtonOnMaxReach and disableDecButtonOnMaxReach

Happy to make any necessary changes after reviewing
