CMB-1022: SimpleIntegerPicker should be display negative sign on the left side of value

### Issue
SimpleIntegerPicker should work the same as LTR in RTL.

### Fix
Adding direction: ltr on top of component and removing rtl specific CSS code.
Adding negative values on sample for testing.
Removing ilib formatting from code.
