Add Sanitize UI (#4123)

# Description of Changes

Implementation of Sanitize UI for V2.

Also removes parameter validation from standard tool hooks because the
logic would have to be duplicated between parameter handling and
operation hooks, and the nicer workflow is for the tools to reject using
the Go button if the validation fails, rather than the operation hook
checking it, since that can't appear in the UI.
