Stop preserving bounds in tool input schemas (#40966)

## What changed

Remove `minimum`, `maximum`, and `maxLength` from the supported tool input
schema representation. Schema parsing now drops these bounds instead of
including them in generated tool declarations, including declarations for
reserved history and notes tools.
