Toggle switch

**Is your feature request related to a problem? Please describe.**
Toggle switches are regularly used. yet there is no default toggle switch for HTML.

**Describe the solution you'd like**
Would be nice to be able to quickly add a toggle switch through chimera instead of having to manually style an input checkbox element. Something like input type="toggle"

**Describe alternatives you've considered**
Styling an input type=checkbox manually.

**Additional context**

The issue names no file, test, or entry point. Start by locating the existing checkbox styling and package entry point, then determine the toggle's markup, states, and accessibility requirements. Done means Chimera provides a usable toggle without requiring manual checkbox styling.
