BREAKING CHANGES
## Core Components
Removes the `--width` and `--height` variables from the following components, in favor of CSS:
- Button
- FAB Button
- Checkbox
- Removes the `--width`/`--height` and adds a `--size` variable that is set on the width and height, allowing width and height to still be set and border-radius to still use it as a variable
- Radio
- Removes the `--width`/`--height` and `--inner-width`/`--inner-height` variables. Calculates inner values based on parent element size.
## Overlay Components
The following components have all be converted to shadow (or scoped) and have CSS variables for width/height:
- Action Sheet _(scoped)_
- Alert _(scoped)_
- Loading _(scoped)_
- Menu _(shadow)_
- Modal _(scoped)_
- Picker _(scoped)_
- Popover _(scoped)_
- Toast _(shadow)_
The above components will now have the following CSS variables for consistency among overlays:
| Name |
| ----------------- |
| `--height` |
| `--max-height` |
| `--max-width` |
| `--min-height` |
| `--min-width` |
| `--width` |
If the component does not set the value, it will default to `auto`.
## Removed CSS Variables
The following CSS properties have been removed:
| Component | Property | Reason |
| ---------------| --------------------| --------------------------------|
| **Button** | `--height` | Use CSS instead |
| **Button** | `--margin-bottom` | Use CSS instead |
| **Button** | `--margin-end` | Use CSS instead |

| **Radio** | `--inner-height` | Calculated based on parent |
| **Radio** | `--inner-width` | Calculated based on parent |
- style all slotted content to order properly in a toolbar, not only buttons
- removes duplicated sass variables
- use current color in select so icon will inherit toolbar color
BREAKING CHANGES
- Removes `--icon-color` and `--placeholder-color` from select in favor of inheritance with opacity
* style(theming): clean up sass TODOs
* fix(item): use proper padding on small buttons in an item
* refactor(components): remove color from unused components
* chore(components): update build files to remove color
* fix(tab-bar): remove unused layout prop
* test(segment): add custom test and update standalone
* docs(segment): update usage examples to remove layout
* test(segment): update tests to remove layout
* test(tab-bar): update tests to remove layout
* fix(segment): set the colors in the parent segment
but use them in the child segment button
This allows the user to customize all of the segment buttons from segment, while still allowing the `color` property to take precedence, and they can also edit the segment button colors directly if desired.
This actually fixes some bugs surrounding colors and allows customization for a segment inside of a toolbar.
