[PLAY-1181] Circle Icon kit: fix sizing error when global spacing props are used

[ElisaShapiro]

What does this PR do? A clear and concise description with your runway ticket url.
PLAY-1181 prevents global spacing props (margin and padding) from altering the size of the circle icon kit by adding size to the classname.

ToDo/Breaking Change consideration:

• This will add word size on iconcircle kits but the actual size will remain the same. The only thing we need to do is make sure iconcircle kits with size on are not being targeted anywhere in Nitro so we can safely update the classname.
• One instance found here.

Screenshots: Screenshots to visualize your addition/change
Before (from example CSB): when present, a padding or margin larger than the Icon Circle's prescribed size causes the size to change to the largest prop value.

After React:

After Rails:

How to test? Steps to confirm the desired behavior:

1. Go to code sandbox (will update with link once created with alpha)
2. Create IconCircle example with any size, plus padding and/or margin of any size.
3. The resultant IconCircle displaying on the left should display an IconCircle of the indicated size, with a padding and/or margin if given of the correct value. The size of the IconCircle should NOT be altered to the largest size given to any of the size/padding/margin props.

I could not find any instances in Nitro where a selector is specifically targeting pb_icon_circle_kit with _size.
