Flatten UI Style properties that use Size + remove Size (#8548)
# Objective

- Simplify API and make authoring styles easier

See:
https://github.com/bevyengine/bevy/issues/8540#issuecomment-1536177102

## Solution

- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,
`max_height`, `row_gap`, and `column_gap` properties

---

## Changelog

- Flattened `Style` properties that have a `Size` value directly into
`Style`

## Migration Guide

- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use
the new properties instead.
