Cleanup on inputs:

* Remove the !important from checkbox and radio border color
* Remove the redundant #wpbody select rule
* Add checkbox and radio inputs to the standard :focus style rules for inputs
* Remove custom border and box shadow styles from .login inputs
* Don't remove the default outline from select elements since webkit doesn't allow borders on selects

Fixes #26120.
