docs(breadcrumb, checkbox, clearbutton, coachindicator): Site Docs to Storybook

[marissahuysentruyt]

Description

This PR continues migrating documentation from the docs site into Storybook. The focus is on breadcrumb, checkbox, clearbutton and coachindicator. All variants of the component should now be displayed on the Storybook Docs page.

• breadcrumb: new MDX docs page and 3 docs-only stories
• checkbox: new MDX docs page, usage notes and a docs-only story
• clearbutton: new MDX docs page and additional docs (Usage Notes) regarding proper icon size
• coachindicator: new MDX docs page

This PR doesn't need a changeset since it's docs-only.

@rise-erpelding thanks for taking a second look after the rebase.

"Default" vs. "Standard"

I changed the story name back to "Default": https://github.com/adobe/spectrum-css/pull/2793/commits/4d0344385cf8194ec930852987bf8bd1360829f4

There is an "Overbackground" variant on the docs site for clear button that I had noticed before, this looks a lot like static white (which is a variant that Close button has). This isn't in Storybook, but maybe there's a reason?

OverBackground got moved to vrt-only when modes got merged. I left it there, but I can ask Cassondra if she wants it back on the docs page.

For posterity, the static white & static black stories are considered "advanced" settings for particular downstream use cases, but they are "not things we wanted to surface widely."
