frontend-plugin-api, frontend-app-api: API review cleanup

Remove @backstage/core-plugin-api leakage from the
@backstage/frontend-app-api public API surface. Rename PluginOptions
to CreateFrontendPluginOptions with a deprecated alias. Remove
ResolvedExtensionInputs from the main @backstage/frontend-plugin-api
entry point.
