Opt into static_cache for component config entities

Overview

While profiling I found 243 calls to ConfigEntityVersionReference::getTarget and a lot of hits to CachedStorage for config for the same config entities. By default config entities opt out of static caching. I'm not sure why. But roles and language_content_settings opt-in.

I think XB could see a performance improvement if component entities used static caching.

Proposed resolution

Add static_cache: TRUE, to Component entity definition.
