This also fixes the Select "popover" interface as it is made up of radio buttons
WAI-ARIA Guidelines:
- Tab and Shift + Tab: Move focus into and out of the radio group. When focus moves into a radio group :
- If a radio button is checked, focus is set on the checked button.
- If none of the radio buttons are checked, focus is set on the first radio button in the group.
- Space: checks the focused radio button if it is not already checked.
- Right Arrow and Down Arrow: move focus to the next radio button in the group, uncheck the previously focused button, and check the newly focused button. If focus is on the last button, focus moves to the first button.
- Left Arrow and Up Arrow: move focus to the previous radio button in the group, uncheck the previously focused button, and check the newly focused button. If focus is on the first button, focus moves to the last button.
Closes#21743
Before users had to know the exact opacity that the MD/iOS spec called for in order to change the hover or focused background color. This allows them to change the background without having to know the opacity.
- changes apply to Action Sheet (Buttons), Back Button, Button, FAB Button, Item, Menu Button, Segment Button, Tab Button
- greatly reduces the requirement by users to set the background hover, focused states for dark modes and custom themes, also eliminates the need to know what the hover opacity is for each based on the spec
- updates the MD dark theme per their spec
- adds a component guide for internal use changing Ionic components

BREAKING CHANGE:
*Activated Class*
The `activated` class that is automatically added to buttons on press has been renamed to `ion-activated`. This will be more consistent with our `ion-focused` class we add and also will reduce conflicts with user's CSS.
*CSS Variables*
The `--background-hover`, `--background-focused` and `--background-activated` CSS variables on components that render native buttons will now have an opacity automatically set. If you are setting any of these like the following:
```
--background-hover: rgba(44, 44, 44, 0.08);
```
You will likely not see a hover state anymore. It should be updated to only set the desired color:
```
--background-hover: rgba(44, 44, 44);
```
If the opacity desired is something other than what the spec asks for, use:
```
--background-hover: rgba(44, 44, 44);
--background-hover-opacity: 1;
```
BREAKING CHANGE:
The following components have been updated to remove the checked or selected properties:
- Radio
- Segment Button
- Select
Developers should set the value property on the respective parent components in order to managed checked/selected status.

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`.
