DEV: Enable @cached decorator for themes and plugins (#19261)

Browse Source 
`ember-cached-decorator-polyfill` uses a Babel transformation to apply this polyfill in core. Adding that Babel transformation to themes and plugins will be complex, so we use this to patch it at runtime. This can be removed once `@glimmer/tracking` is updated to a version
with native `@cached` support.
