Add asAlpha to tree package

[noencke]

This will allow future APIs that follow the same pattern to share the same common asAlpha API.
This also aligns the tree API with the recently introduced container-runtime API.

Pull Request Overview

This PR renames the asTreeViewAlpha function to asAlpha to allow future APIs that follow the same pattern to share a common API for accessing alpha functionality. This aligns the tree API with a recently introduced container-runtime API pattern.

• Replaces all imports and usages of asTreeViewAlpha with asAlpha
• Moves the function implementation from simple-tree/api/tree.ts to a new api.ts file at the package root
• Updates API documentation and exports to reflect the rename

[Josmithr]

Nit: should we maybe leave a @privateRemarks block noting that package-internal usage is not deprecated, just external?

[Josmithr]

Do we have any usages elsewhere in the repo that we should migrate in this PR?

Coming back just for future reference, with a new (to me, at least) reason why we avoid inline code blocks in changeset headings (we missed it this time, oops): it breaks ToC links in the final release notes (probably only if the heading starts with a code block like in this case). All links work except that one.
