Remove deprecated typography components

[laurkim]

WHY are these changes introduced?

Resolves #6511.

Now that Shopify/web has been migrated to use the Text component, we can safely remove the 6 deprecated typography components.

Note: The 3 chromatic changes are related to other changes in the v11 branch and not this PR.

WHAT is this pull request doing?

Removes DisplayText, Heading, Subheading, Caption, TextStyle, and VisuallyHidden.
