[ui/public/utils] Move items into agg_types

[lukeelmers]

Part of #51560

There are a few utils in src/legacy/ui/public/utils that are primarily used by ui/agg_types. We should move these into agg_types so that they can eventually be migrated along with the rest of that module.

• ordinal_suffix 👉ui/agg_types @alexwizp [[ui/public/utils] Move items into agg_types #52744]
• Double check that any relevant tests are moved as well
• Document changes[0] in the ui/public cleanup section of the dev docs issue Dev Docs entry: ui/public & angular cleanup 7.6 #43511

[0] Let's document all of these as "deprecated" until we know which (if any) we want to expose in new platform contracts.
