feat(avatar): add styles for xsmall size in ionic theme (#29548)

Issue number: internal

---------

## What is the current behavior?
Avatar does not have styles for the `"xsmall"` size in the ionic theme.

## What is the new behavior?
- Adds the styles for the xsmall size (width, height, padding, font
size, font weight and line height)
- Adds e2e test for xsmall size to the existing avatar test for sizes

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

## Other information
