feat(pie-list-item): DSW-2910 base list item

[matthewhardern]

Describe your changes (can list changeset entries if preferable)

This PR adds the new pie-list-item component to the PIE Design System with the following structure:

Component Definition: Creates a basic PieListItem class that extends LitElement
TypeScript Types:

An empty ListItemProps interface (with a TODO comment for future implementation)
React typings through ReactBaseType

Web Component Registration:

Registers custom element with tag name pie-list-item
Sets up proper TypeScript definitions for HTML element map

Build Configuration: Updates Vite config to build the component as a separate module
File Structure: Properly organized under the src/pie-list-item/ directory

The PR effectively creates a minimal skeleton for the pie-list-item component, setting up the necessary structure and build configuration, but doesn't yet implement any actual functionality or styling. It's intended as a foundation for further development of the component.
