Add CSS Utility for `auto` width and height Properties (#24249)

Add CSS Utility for `auto` width and height Properties (#24249)

Currently bootstrap only provides 4 variations of `width` and `height` css utilities, which are:

1. 25%
2. 50%
3. 75%
4. 100%.

Here, I'm adding `auto` to the list. This is useful when we need to reset the width/height value
back to the browser default value at some point.
