Updates all of the global variables to make sure their naming is consistent, their default values are correct, they are used properly by the related components, and remove any that are not used.
- removes some of the non mode-specific global Sass variables
- updates the md and ios values so that the default is the css variable
with different fallbacks
- removes non-color related css variables from the global file
- fixes item so it uses the background color that is set by the global
file

Fixes#15989Fixes#15559
Adds the following CSS properties to item:
```
--highlight-color-focused
--highlight-color-valid
--highlight-color-invalid
--highlight-height
```
This also fixes an issue where we were showing the highlight on items
with no lines, and shows inset vs full properly. Adds documentation and tests for input focus.
