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;
```
- removes mode-less component classes from the internal CSS, use element instead
- adds mode specific classes `md` or `ios` for styling inside of shadow components
- adds e2e test that verifies mode classes exist on all ionic components, plus checks for specific classes that the components need for internal styling
fixes#17608
BREAKING CHANGES
The outer-content class has been removed in favor of setting the color in your app instead:
```
.outer-content {
--background: #f2f2f2;
}
```
This reimplements chip, removing the extraneous chip-button and chip-icon components and updating the design to match the updated Material Design spec.
- updates components to use shadow DOM or scoped if they require css variables
- moves global styles to an external stylesheet that needs to be imported
- adds support for additional colors and removes the Sass loops to generate colors for each component
- several property renames, bug fixes, and test updates
